ОтветитьУдалитьEnglish is often used in the mathematical sciences, so the video is very informative and useful for people involved in mathematics.
In the course of the video, we learn about such a wonderful (though not everyone's favorite) world of fractions. The world of fractions is a very insidious and dangerous environment. A lot of rules and nuances can turn an elementary-looking fraction into something terrible and unappealing in appearance. The same operations of addition, subtraction, multiplication and division were described in great detail and not loaded.
I advised my sister to watch the video, in response received a bunch of bewilderment and indignation at the expense of the existence of such a strange thing as a fraction (the child is in second grade).
Then I acted smarter and gave my older sister a look, there the reaction was positive. Even a little surprise was present.
I watched the video and found out a lot of useful things. Post such lessons more often.

A fraction in mathematics is a number consisting of one or more parts (fractions) of a unit. To imagine this, let's take a pie and divide it into several equal parts-let's say by 6(but you can take any number). Each piece of the pie will be one share. If we write it as or 1/6 (read "one sixth"), then it will be a fraction.

This video contains a lot of useful and interesting information. Operations with fractions, in my opinion, are not so difficult, but many have problems when comparing fractional numbers. But after watching this video, there should be no questions left on this topic. You can compare both positive and negative fractions.This happens using cross multiplication: the numerator of one fraction is multiplied by the denominator of the other fraction. For example, 4/5 and 2/7, we have to multiply 4 by 7, 2 by 5. As a result, we get 28 and 10, which means 4/5 is larger.
ОтветитьУдалитьSuleimanova Saida
This video is very useful and, most importantly, it is easy to explain everything. There are strange moments when calculating fractions. Here, both positive and negative values are compared using a proportion (cross-multiplication). For example, 10/11 and 4/7 are compared like this: 10 is multiplied by 7, and 4 by 11. The result is that 70 is greater than 44. And thus we get that 10/11 is greater than 4/7.
ОтветитьУдалитьGamidova Asiyat.
A short video explains how to compare fractions correctly.This is done quite simply, the numerator of the first fraction is multiplied by the denominator of the other fraction and vice versa.For example, 3/4 and 5/7, 3 multiplied by 7 we get 21 and 5 multiplied by 4 we get 20 and compare the two obtained numbers 21>20.With negative fractions, everything is done exactly the same.I am sure that this video will help many people understand this topic.

ОтветитьУдалитьСаидова Рукият 2к4г
This way of comparing rational numbers is interesting one. Because of you can find the answer easily without bringing fraction into rational number. You can make it without any hard with natural number in numerator, but when you get a negative fraction, you have to remember, that you compare not module of there numerators, you should compare those numbers as a negative ones. So, I mean, that negative number which is smaller than zero and module of this number is bigger than another given negative number, so it means that this number is smaller.
ОтветитьУдалитьMahmudov Omar
For comparing fractions with equal denominators, we simply have to compare their numerators.
ОтветитьУдалитьFor comparing fractions with unlike denominators, we have to start by finding the least common denominator(LCM) to make the denominators the same.
When the denominators are made the same, the fraction with the larger numerator is the larger fraction.
For example 1/2 and 2/5.
While you compare negative numerals you should remember, that the larger the absolute value of a number, the smaller it is.
For example -1/2 is greater than -2/3, while 2/3 is greater than -1/2.
I will not write that the video was useful and informative, because it explains school math material. We've all studied it and we all know it. The video tells about a simple way to compare two fractions by multiplying the numerator of one fraction by the denominator of the other, and vice versa.

2)A decimal number is the number that is written from the usual digits for us, namely from the decimal system. In the numerical decimal system, there are only ten (which is why such a name): 0 1 2 3 4 5 6 7 8 and 9.
3) Units are all integers.
4) Read decimal:It is necessary to read each number separately and after the integer part it is necessary to read a point.
5)If you move one position to the right, you get a number ten times greater than the previous one. If you move one position to the left, you get a number ten times less than the previous one.

ОтветитьУдалитьFractions are my favorite topic, so I watched this video with great pleasure. This video talks about comparing fractions. We can compare both positive and negative fractions. To compare two fractions means to understand which one is bigger and which one is smaller.
For example: 5/12 and 9/16 in order to compare them, we need to find the largest common coefficient, this is the number 48. Then we need to add additional multipliers to the first fraction 5/12, this is the number from the quotient 48: 12 = 4, for the second fraction 48: 16 = 3. Multiplying 4 by the numerator of the first fraction and 3 by the numerator of the second fraction, we end up with 20/48 and 27/48 . So 5/12 is less than 9/16 . Negative numbers work in the opposite direction, because as the numbers increase, their values decrease.

2. A decimal number is a number that consists of the digits we are familiar with, namely, the decimal system of calculus.
3. A fraction is a number entry in mathematics in which a and b are numbers or expressions. In fact, this is just one of the forms in which a number can be represented.
4. They are read as follows: what is read before the comma as usual, then it is necessary to say integers, and everything after the commas will depend on the numbers of digits. If there is one digit after the decimal point, the decimal point is read.
5. To increase the decimal fraction 6.3 tenfold, it is enough to move the decimal point to the right by one digit and vice versa, if you reduce it, then you need to move it to the left.

According to the rule, when multiplying an integer by a fraction, the original number is multiplied by the numerator of the fraction and divided by the denominator, and when dividing by a fraction, the original number is multiplied by the denominator and divided by the numerator, that is, it seems to be multiplied by an inverted fraction.
4. Because if the integer part is incorrectly set, the number it self may change, become larger or smaller.

Fractions are really not an easy topic. For many it is very difficult. This video explains them very well. I think it can be very helpful for those who have just started learning fractions.
ОтветитьУдалитьHere is a simple comparison of rational fractions.
For comparing fractions with equal denominators, we simply have to compare their numerators. For compare fractions with different denominators, find the smallest common denominator.
While you compare negative numerals you should remember, that the larger the absolute value of a number, the smaller it is.
If you have the patience to learn fractions, I think after watching this video there will be no questions left. Thank you for such a useful and informative video.

After watching video "How to compare fractions fast and easy" , I learned about a new and interesting method for comparing fractions.This way is much easier.When you have two fractions for compare them, you need to multiply the numerator of the first fraction by the denominator of the second fraction, then multiply the numerator of the second fraction by the denominator of the first fraction and then compare the resulting numerators, if the numerator of the first fraction is greater than the numerator of the second fraction, then the first fraction is greater than the second fractions , if the fractions are negative, then vice versa.

*This method is mush easier.
УдалитьI just watched a very interesting and informative video for me about how to compare two fractions . To be honest, even though I am already studying at the institute, but before this video I did not know this way of comparing fractions. This method of comparing fractions is as follows: when you have two fractions for compare them, you need to multiply the numerator of the first fraction by the denominator of the second fraction, then multiply the numerator of the second fraction by the denominator of the first fraction and then compare the resulting numerators, if the numerator of the first fraction is greater than the numerator of the second fraction, then the first fraction is greater than the second fractions , if the fractions are negative, then vice versa.
ОтветитьУдалитьThe purpose of this video is to explain about such elementary and basic arithmetic operations as: addition, subtraction, multiplication and division.
ОтветитьУдалитьIf, when adding or subtracting fractions, the fractions have the same denominators, the necessary operations are performed in the numerators. For example, three sevenths plus two sevenths equals five sevenths.
The following example was considered: three-fifths plus one-fourth. Since the denominators of fractions are different, it is necessary to reduce them to a common denominator, which is divisible by both five and four. This number is 20. The first numerator must be multiplied by four, and the second by five. The answer will be 17/20.
In order to multiply two fractions, you need to multiply the numerators and denominators separately. And, if necessary, the fraction must be reduced.
As for division, the video says that when dividing, the first fraction should be left as is, the second fraction should be turned over, and the division sign should be changed to the multiplication sign.
The video tutorial was helpful and the explanation was quite clear.

1) The arithmetic of numbers in decimal form is completely consistent with the arithmetic of numbers in fractional form. Decimal numbers can be added, subtracted, multiplied and divided. Before performing addition and subtraction with fractional numerals, the fractions must have common denominator. When multiplying with fractions, we find the product of the numerators and the product of denominators. When dividing fractions, we must turn the second fraction over and then multiply with the first. The only thing that will change is that we only have to write the decimals so that all the decimal points lie on the same vertical line. This keeps each digit in its proper place value position.

ОтветитьУдалить1) What is a decimal point for?
This dot is called a decimal point, and it separates parts of a whole number from the whole number.These parts are called decimals. A decimal is a number less than 1. Whole numbers - also called units - are greater than or equal to 1.The decimal point basically signifies "and" as a way to separate these two different kinds of numbers. Decimals are found to the right of the decimal point, and units are found to the left of the decimal point.
2) What is a decimal numeral?
A decimal is a number less than 1.
3) What is a unit?
Whole numbers - also called units - are greater than or equal to 1.
4) In what ways do you read decimals?
If you want to write out four whole units and 12 decimal parts, it would look like this. You can read this as "four point one two" or as "four and twelve one-hundredths."
5) What will you get if you move one position to the right /left?
The decimal number system is based on preceding powers of 10. This means it's a series of numbers where each number is ten times bigger or smaller than the last. If we move to the left of the decimal point, each position is 10 times bigger. If we move to the right,
each position is 10 times smaller.

2) What are the principle steps in multiplying decimals?
Step 1. Complete the multiplication as you normally would, as if the decimal was not there.
Step 2. Determine the total number of digits after the decimal points in the number is that you're multiplying together.
Step 3. Place the same number of digits behind the decimal point in the product.
3) What is the difference between multiplying integers and decimals?
You do the multiplication in exactly the same way. The only extra thing is that when multiplying decimals, you need to place the decimal point (or decimal comma - depending on your country) in the correct position. If one number has, for example, 3 digits after the decimal point, and the other 4, you need to place the decimal point in the result (before eliminating unnecessary zeros) in such a way that there are, in this example, 7 digits (3 + 4) to the right of the decimal point.

This video contains a lot of useful and interesting information. Operations with fractions, in my opinion, are not so difficult, but many have problems when comparing fractional numbers. But after watching this video, there should be no questions left on this topic. You can compare both positive and negative fractions.This happens using cross multiplication: the numerator of one fraction is multiplied by the denominator of the other fraction. For example, 4/5 and 2/7, we have to multiply 4 by 7, 2 by 5. As a result, we get 28 and 10, which means 4/5 is larger.
ОтветитьУдалитьThis video is very useful and, most importantly, it is easy to explain everything. There are strange moments when calculating fractions. Here, both positive and negative values are compared using a proportion (cross-multiplication). For example, 10/11 and 4/7 are compared like this: 10 is multiplied by 7, and 4 by 11. The result is that 70 is greater than 44. And thus we get that 10/11 is greater than 4/7.
ОтветитьУдалитьVery informative video, learned a lot of new things. Thank you very much.

ОтветитьУдалитьwe can see a very interesting method which is shown in this video.
ОтветитьУдалитьinstead of usual comparison of two given fractions, we just compare two numbers which we get in a certain way. we take the numerator of the first fraction and the denominator of the second one. we multiply these numerator and denominator and write there multiplication near the first fraction. then we take the denominator of the first fraction and the numerator of the second one. we do the same as in the first case and write their multiplication near the second fraction. and now we compare these two numbers : the first multiplication represents the first fraction, and the second multiplication represents the second fraction. we compare them as usual whole numbers.
we must remember that if we have two negative numerals to compare, the greatest of them will be the number with the least module

ОтветитьУдалитьThis (third) video talks about how to compare both positive and negative fractions.
ОтветитьУдалитьIf we need to compare the left (first) fraction with the right (second), then we need to do the following:
1. Multiply the numerator of the left fraction by the denominator of the right, write down the resulting product on the left side.
2. Multiply the numerator of the right fraction by the denominator of the left, write the resulting number on the right side.
3. Compare the right side with the left side. if the left one is greater, then the first fraction is greater, otherwise they are either equal or the second fraction is greater.
4. We put the sign of inequality or equality.
Thanks for the informative video!

In this video, that chick told how to find out which of the two given fractions is greated. This is done like this, the denominator of the first fraction is multiplied by the numerator of the second (this will be the value of the second fraction), then the denominator of the second fraction is multiplied by the numerator of the first fraction (this will be the value of the first fraction). After that, these values are compared. For example, given fractions are -9/7 and 3/5. To find out which of these fractions is greater, we multiply 7 by 3, equal to 21, and 5 by -9, equal to -45, we compare these values, 21 is greater than -45. So 3/5 is greater than -9/7
ОтветитьУдалитьКоментарий Магомедова Арслана 2 курс 4 группа
In order to compare two fractions, you need to multiply the denominator of the first fraction by the numerator of the second - this will be the value of the second fraction, and multiply the denominator of the second fraction by the numerator of the first - this will be the value of the first fraction. Example, find out which fraction is greater than 1/5 or 3/7. Multiplying 5 by 3 equals 15 is the value of the second fraction, and multiplying 7 by 1 is 7 is the value of the first fraction. 7 < 15 means 1/5 < 3/7.

1.The decimal point is needed to separate the whole part of the decimal number.
ОтветитьУдалить2.Multiplication of decimal fractions practically does not differ from the multiplication of basic ones; when multiplying, we must pretend that there is no point of view. And after having already multiplied, we must determine exactly where the standing point will be.
3)The difference is that when multiplying foci in points it is not required, it is necessary for multiplying decimal fords.
4. For example, the number 1.99 we will read as 1 whole units and 99 decimal parts
5) If we move one position to the right, we will get a number ten times larger than the previous one, if we move one position to the left, we will get a number ten times smaller than the previous one.

1)You should become efficient in using the four basic operations involving decimals—addition, subtraction, multiplication, and division.
ОтветитьУдалить2)To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
3)The only difference between multiplying whole numbers and multiplying decimals is that we have the added step of moving the decimal point after performing the multiplication when multiplying decimals.
4)When adding numbers with decimals the most important thing is to line up the decimal points of the numbers you are adding. If you do this, adding decimals is just like normal adding.
a decimal point separates parts of a whole number from the whole number. these parts are called decimals. a decimal is a number less than one. the others parts are called units and they are greater or equal to one.
ОтветитьУдалитьa decimal point separates units and decimals. decimals at the right of the decimal point, and units are to the left of it.
as for reading the decimal numbers, there are some ways for it. for example, 4.12. we can read it as four point one two, or four and twelve one hundreds.
if we move to the left each position is ten time bigger, and if we move to the right each position is ten time smaller
1. we can do all the four basic operations of arithmetics with the decimal numbers too. they are : addition, subtraction, multiplication and division
2. to multiply two decimal numbers we need to multiply them like rational numbers don’t pay attention to the decimals points. after multiplication we just count how many numbers are there on the right of both decimal points and shift the decimal point of the product with the number of those numbers on the right of the decimal point in an opposite way (shift it to the left)
3. when we multiply integers we don’t think about shifting the decimal point because the decimals are equal to zero
4. we must be careful when marking a decimal point in the product because it’s very easy to make a mistake counting the numbers of decimals of factors
