Question

Malcolm started with a board that was 5 3/5 feet long. He then cut off a section that was 1 5/12 feet long. How much of the board is left?

Answer 1

4 11/60

Explanation:

We are to subtract 15/12 from 5 3/5

`5(3)/(5)` -
`1(5)/(12)`

The least common multiple is 60

`4(36 - 25)/(60)`

`4(11)/(60)`
