Exercise 2 Page 329

Rewrite the mixed number as an improper fraction. Then divide the fractions.

8 23

Practice makes perfect

Let's find the quotient for the given division. 6 12 ÷ 3/4 We will start by rewriting the mixed number as an improper fraction.

6 12 ÷ 3/4
6*2 + 1/2 ÷ 3/4
12+1/2 ÷ 3/4
13/2 ÷ 3/4

Recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 13/2 ÷ 3/4 = 13/2* 4/3 Next, we multiply the numerators and the denominators.

13/2* 4/3
52/6
26/3
8 23

Now, let's check our answer. To do so, we will multiply the quotient, 8 23, by the divisor, 34.

8 23 * 3/4
â–¼
Write mixed number as a fraction
8*3+2/3 * 3/4
24+2/3 * 3/4
26/3 * 3/4
78/12
13/2
6 12

As we can see, the result is the dividend. So, we know our answer is correct.
