Question

What is 3/10 ÷ by 4/5

Answer 1

Your answer to the question is 3/8

Answer 2

`(3)/(10)` ÷
`(4)/(5)` equals
`(3)/(8)`.

First, apply this rule: a ÷
`(b)/(c)` = a ×
`(c)/(b)`. Your problem should look like:
`(3)/(10)` ×
`(5)/(4)`.
Second, apply this rule:
`(a)/(b)` ×
`(c)/(d)` =
`(ac)/(bd)`. Your problem should look like:
`(3x5)/(10x4)`.
Third, simplify 3 × 5 to get 15. Your problem should look like:
`(15)/(10x4)`.
Fourth, simplify 10 × 4 to get 40. Your problem should look like:
`(15)/(40)`.
Fifth, simplify. Your problem should look like:
`(3)/(8)` which is the answer.
