Question

Mr. Sheffo wants to make a shelf with boards that are 1 1/4 feet long. If he has an 18-foot board, how many pieces can he cut from the big board?

Answer 1

Given length of the long board = 18 feet

Mr. Sheffo wants to make shelf with boards that are =
`1(1)/(4)` feet or
`(5)/(4)` feet

So, the number of pieces he can cut from the long board are =

`(18)/((5)/(4))`

=
`(18*4)/(5)` =
`(72)/(5)` =
`14(2)/(5)` boards

As the number can be a whole number, so 14 boards is the answer.
