Dividing Word Problems

Introduction to dividing word problems:

Division is one of the arithmetic operations and also it is the inverse of multiplication. We know that the solution of dividing two rational numbers is another rational number when the divisor is not Zero. Division of any number by zero is not defined. Because of zero is multiplied by any particular number will always result in a product of zero. If we can enter these types of numbers into the calculator then error message is displayed.
Examples of dividing word problems:


Dividing word problem 1:


Jack invites 12 friends to his Wedding party. He distributes 72 balloons equally among them. How many balloons did each friend get?

Solution:

We can find the number of balloons per each by using the division method.

Therefore Total number of balloons= 72

Total person= 12

Therefore, `72/12` `= 6`

Answer: 6

Dividing word problem 2:


A board game has 45 total coins. There are equal number of coins of 5 different colors. How many coins are there of each color?

Solution:

 Total number of coins= 45

 Total number of colors= 5

So, `45/5` `= 9`

Here 45 is 9 times of 5

Answer: 9
