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 = $1\frac{1}{4}$ feet or $\frac{5}{4}$ feet

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

$\frac{18}{\frac{5}{4}}$

= $\frac{18*4}{5}$ = $\frac{72}{5}$ = $14\frac{2}{5}$ boards

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