Rob bought a board that was 9 ½ feet long. He cut off two pieces that were each 3 ¾ feet long. How much of the board is left?

Question

what is the rest?

Answer 1

3 3/4 times 2 = 6 6/4 = 6 3/2 = 6 + 1 1/2 = 7 1/2

9 1/2 minus 7 1/2 = 2 feet left

or work the problem with decimals

9 1/2 = 9.5

3 3/4 = 3.75

3.75 times 2 = (3.75)(2) = 7.5

9.5 - 7.5 = 2 feet
