Exercise 2 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.

5/6

Practice makes perfect
Before we evaluate the expression, let's first rewrite the mixed number as a fractions. Also, remember that each integer can be written as a fraction with a denominator of 1.
4 16Ă· 5
4* 6+1/6Ă·5
24+1/6Ă·5
25/6Ă·5
25/6Ă·5/1
Recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 25/6Ă·5/1=25/6*1/5 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!
25/6*1/5
25* 1/6* 5
25/30
Note that 25 and 30 have a common factor, which is 5. Let's simplify the quotient 2530 by dividing both the numerator and the denominator by 5.
25/30
25 Ă· 5/30 Ă· 5
5/6
There are no more common factors between the numerator and the denominator. Also, since the numerator is less than the denominator, we cannot write the quotient as a mixed number.
