Question

Rafi had a board that was 15 1/2 ft long. He cut three pieces off the board that are each 3 7/8 ft long. How much of the board is left?

Answer 1

The simplest way to solve this is to set up an equation that includes all parts of the problem.

The best equation would look like this:

`15.5 - 3.875(3) = x`

`15.5` being the original length of the board

`3.875(3)` being the length cut off times the number of times being cut off

And `x` being the final length

All we do from here is to solve.

`15.5 - 11.625 = x`

`3.375 = x`

Simplify and get:

`x = 3 3/8 ft.`
