Answer 1

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*(4)/(1)= 12`

2) 7 ÷ (1/2) =
`7 * (2)/(1)=14`

3) (1/5) ÷ (1/20) =
`(1)/(5)*(20)/(1)=4`

4) (1/2) ÷ (1/10) =
`(1)/(2)*(10)/(1)=5`

5) (1/7) ÷ 3 =
`(1)/(7)*(1)/(3)=(1)/(21)`
