Answer 1

Answer:

Step-by-step explanation:

Use KCF method for fraction division.

Keep the first fraction

Change the operation to multiplication

Flip the second fraction.

1) 3÷ (1/4) = $3*\frac{4}{1}= 12$

2) 7 ÷ (1/2) = $7 * \frac{2}{1}=14$

3) (1/5) ÷ (1/20) = $\frac{1}{5}*\frac{20}{1}=4$

4) (1/2) ÷ (1/10) = $\frac{1}{2}*\frac{10}{1}=5$

5) (1/7) ÷ 3 = $\frac{1}{7}*\frac{1}{3}=\frac{1}{21}$
