Question

Julia has saved 108 sand dollars and wants to give them away equally to x friends. Write an expression to show how many sand dollars each of Julia’s friends will receive. Then, find the total number of sand dollars each of Julia’s friends will get if Julia gives them to 12 friends.

Answer 1

• s = 108/x . . . . s = sand dollars each friend gets
• each of the 12 friends gets 9 sand dollars

Explanation:

The point of a fraction is to express the size of something that has been divided into a number of parts equal to the denominator. For example, 1/3 represents the amount when 1 unit is divided into 3 parts.

Here, Julia has 108 that she wants to divide into x parts. The fraction 108/x will tell the size of each part.

When x=12, the fraction becomes 108/12 = 9/1 = 9. Each friend gets 9 sand dollars.
