Exercise 1 Page 71

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. Rewrite your answer as a mixed number.

4 13

Practice makes perfect
Before we evaluate the expression, let's first rewrite the mixed number as a fraction.
3 14÷ 3/4
3* 4+1/4÷3/4
12+1/4÷ 3/4
13/4÷3/4
Recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 13/4÷3/4=13/4*4/3 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!
13/4*4/3
13* 4/4* 3
13* 4/4* 3
13/3
The numerator is greater than the denominator. It means that we can write the answer as a mixed number!
13/3
12+1/3
12/3+1/3
4+1/3
