The question
÷

How it works.
- 01
4/5 ÷ 3/8 is asking a question: how many 3/8s fit inside 4/5?
- 02
Lay 3/8 against it and see how many times it goes.
- 03
2 whole pieces and 2/15 of another fit — so 4/5 ÷ 3/8 = 32/15.
- 04
Now multiply by 8/3 — 3/8 turned over. Same answer.
- 05
So dividing by a fraction is the same as multiplying by it turned over. 4/5 ÷ 3/8 = 32/15.
