Multiplication/division as inverse operations

Hi Friends, today in free answers to math problems session we will focus on Multiplication/division as inverse operations. When we talk about the inverse operation it means the operations that are reverse from the another operation .There are several examples of operations that are inverse with each other as addition and subtraction are the inverse operation as well as integration and differentiation are the inverse operation. Here in this series one of pair of inverse operations are Multiplication and division, for division, multiplication as inverse operations works and for multiplication, division as inverse operations. Also play inverse function worksheets to increase your knowledge.
We take some examples for understanding the multiplication as inverse operations that are as follows:
Example: If there is an expression as 36 / 6 =? Then find the inverse operations of the given expression?
Solution: 36 / 6 = 6,
According to the inverse operation 6 * 6 = 36.
Example: Find the inverse operation of the 150 / 15 =?
Solution: As we know the answer of the given expression is 150 / 15 = 10,
Inverse operation of the given expression is 15 * 10 = 150.
We also define the inverse operation for multiplication that means division as the inverse operation .It will also be explained through the some examples:
Example: If 4 * 5 = 20 then find the inverse operation for given expression?
Solution: As the given expression 4 * 5 =20 then its inverse operation will be division that is denoted as the expression 20 / 4 = 5 and 20 / 5 = 4.
Example: If a given expression is 5 * 7 = 35 then what is the inverse operation for it?
Solution: Inverse operation for the given example is defined by the division operation as
35 / 5 = 7 and 35 / 7 = 5.
