Exercise 10 Page 97

Rewrite the expression so that all of the numbers are fractions. Remember that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction.

15

Practice makes perfect
Before we evaluate the expression, let's first rewrite the expression so that all of the numbers are fractions. Remember that each integer can be written as a fraction with a denominator of 1. 5Ă· 1/3=5/1Ă· 1/3Recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 5/1Ă·1/3=5/1*3/1 When we multiply fractions, we need to remember that the product of two fractions is equal to the product of the numerators divided by the product of the denominators. Let's find the given product!
5/1*3/1
5* 3/1* 1
15/1
15
Our quotient is equal to 15. Because it is an integer, we cannot simplify it further.

Checking Our Answer

We can check our answer by finding the quotient using a calculator. We will compare the quotient of the original numbers to the final answer that we found. Let's find our quotient using a calculator.

Because the calculator found the same number, we know that our answer was correct!
