# ????????? ?? ??????? ?????

Division and multiplication are two different and closely-related operations in mathematics. In this post, we'll explain the need to flip and multiply when we divide a whole number by a fraction. Other than ?????? the ?????, ?? ?? ?? ?????? ?????? ?? ?? ??? ??????? ?? ??? ???? ?? ???? ??? ?? ???? ??????? ?? ?? ?????? ?? ?????? ?? ???? ??, ????? ?? ??????? ?? ????? ?? ??? ?? ?????? ??? ????? ???? ???? ???? ????? ???? ??? ???

We ll understand this with the simple example of 6 2 = 3

The simplest one is to make two groups and divide six into the two groups. But the video will use the size model to explain best how this works. It s like having six things which are divided into groups of size two.

Let s best explain the division of ????? ??? ???????? ?? ??? ??:

???? ?? ?? ?? ?????? ?? ??? ???????? the ?????:

We imagine six blocks of chocolate on the number line from 0 to 6 and divide it by . Don’t be confused because this does not mean to divide six pieces into two halves. It indicates the division of six blocks into half sizes. You can ask your students this question if they have six pieces of chocolate, how many halves would fit in there The answer is two halves would fit into each piece and total halves equal to 12.

?? ??? ?? ???? ?????? ???? ??:

6 => 6 x 2 = 12

?? ????? ??, ???? ????? ???? ???? ?? ??? ??? ?? ?? ???? ?? ?????? ?? ??????? ?? ?? ???????? ?????? ??? ??? ???? ??? ??? ?????? ??? ??? ???? ?? ??? ??? 6 ???? ?? ??? ???? ?????

Now, let's take an example of ???? the ????? that don t have one on the numerator, such as 6 2/3.

???? ?? ?? ??? ??? 1 ???? ??, ?? ??? ?????? ???? ?? ???????? ????? ?? ??? ?????? ??? ?? ??? ??????? (??) ??? ?????, ?? 18 ?? ????? ??? ??, ?? 2/3 ??? ?? ???? ?? ?? gluing ???? 2/3 ??? ??????? ?? ???? ???, ?? ?? ???, ???? 2/3 ???? ?? ?????? ????? ??? ??? ?? ???? ?????? ??? ?? ??? ??? ???? ???, ?? ?? 9 ?? ????? ???

?? ?? ?????????? ???? ?????? ???? ?? ???? ??:

6 2/3 => (6 x 3)/2= 18/2= 9

??? ?? ??? ?? ?? ?????? ???? ??? ????? ?????? ??, you'll understand the pattern more concretely. Once the student has a common understanding of the inversion and multiplication of fractions and learns the trick along with practicing different fractions, the student will have a better understanding of multiplying fractions. Hopefully, this video will help a student better grasp this concept.
