Exercise 3 Page 58

Rewrite the expression so that all of the numbers are fractions.

9030 or 3

Practice makes perfect

Before we evaluate the expression, let's first rewrite the expression so that all of the numbers are fractions.

3 35 ÷ 1 15

a bc=a* c+b/c

3 * 5+3/5 ÷ 1 * 5+1/5

Multiply

15+3/5 ÷ 5+1/5

Add terms

18/5 ÷ 6/5

Recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 18/5 ÷ 6/5 = 18/5 * 5/6 When multiplying fractions, remember that the product of two fractions is equal to the product of the numerators over the product of the denominators.

18/5 * 5/6

Multiply fractions

18 * 5/5 * 6

Multiply

90/30
