Exercise 8 Page 46

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

1/5

Practice makes perfect

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

1 25 ÷ 7

a bc=a* c+b/c

1 * 5+2/5 ÷ 7

Identity Property of Multiplication

5+2/5 ÷ 7

Add terms

7/5 ÷ 7

Write as a fraction

7/5 ÷ 7/1

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

7/5 * 1/7

Multiply fractions

7 * 1/5 * 7

Identity Property of Multiplication

7/5 * 7

Multiply

7/35

a/b=.a /7./.b /7.

7/7/35/7

a/a=1

1/35/7

Calculate quotient

1/5
