Exercise 10 Page 58

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

8414 or 6

Practice makes perfect

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

10 12 ÷ 1 34

a bc=a* c+b/c

10 * 2+1/2 ÷ 1 * 4+3/4

Multiply

20+1/2 ÷ 4+3/4

Add terms

21/2 ÷ 7/4

Recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 21/2 ÷ 7/4 = 21/2 * 4/7 When multiplying fractions, remember that the product of two fractions is equal to the product of the numerators over the product of the denominators.

21/2 * 4/7

Multiply fractions

21 * 4/2 * 7

Multiply

84/14
