Exercise 18 Page 331

2 25

Practice makes perfect

Let's find the quotient for the given division. 6 35 ÷ 2 34 We will start by rewriting the mixed numbers as improper fractions.

6 35 ÷ 2 34
6*5 + 3/5 ÷ 2* 4 + 3/4
30 + 3/5 ÷ 8 + 3/4
33/5 ÷ 11/4

Recall that dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. 33/5 ÷ 11/4 = 33/5 * 4/11 Next, we multiply the numerators and the denominators.

33/5 * 4/11
33*4/5*11
3*4/5*1
12/5
2 25

Now, let's check our answer. To do so, we will multiply the quotient, 2 25, by the divisor, 2 34.

2 25 * 2 34
2 * 5 + 2/5 * 2 * 4 + 3/4
10+ 2/5 * 8 + 3/4
12/5 * 11/4
132/20
33/5
6 35

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