6/8 divide by 8/12 A. 9/2 B. 8/9 C. 9/8 D. 9/32

Musya8 [376]

Answer:

C. 9/8

Step-by-step explanation:

$\frac{6}{8} \div \frac{8}{12}$

Use KCF which means Keep the first fraction, Change the second fraction by flipping it and change the division sign to a multiplication symbol:

$\frac{6}{8} \times \frac{12}{8}$

multiply the numerator together:

6 × 12 = 72

multiply the denominator together:

8 × 8 = 64

now the fraction is:

$\frac{72}{64}$

simplify further by dividing both numbers by 8:

72 ÷ 8 = 9

64 ÷ 8 = 8

so the fraction is 9/8
