Question

Raymond has two seven foot long boards, and wants to cut fifteen inch long peices from each; what is the greatest number of peices Raymond can cut?

Answer 1

7ft = 84in   84  ÷  15 =  5.6 pieces he can cut from each board.  Since .6 is not a whole piece measuring 15 inches long, he can only cut 5 pieces from each board.

So, 5 x 2 = 10

He would be able to cut 10 pieces measuring 15 inches long.

Hope this helps :)

Answer 2

It will be double whatever he can cut from one board, not what he can cut from both boards treated as a single 14ft board.
He wants 15 inch pieces.
Each board in 7 x 12 = 84 inches.
How many 15 inches from 84? 84 / 15 = 5.6. So that is 5 because we have to round down.
Since he has two boards the total number is 5 x 2 = 10.
