Exercise 22 Page 34

Rewrite the whole number 5 as a fraction. Multiply both the numerators and the denominators.

35/2 or 17 12

Practice makes perfect

Before we can find the quotient, we will first rewrite the whole number 5 as a fraction.

5÷ 2/7

Write as a fraction

5/1÷2/7

Next, recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 5/1÷2/7=5/1* 7/2 When multiplying fractions, remember that the product of two fractions is equal to the product of the numerators over the product of the denominators.

5/1* 7/2

Multiply fractions

5* 7/1* 2

Multiply

35/2

We can also rewrite this answer as a mixed number.
