Question

Mr. Gengel wants to make a shelf with boards that are 1 1/3 feet long. If he has an 18 foot board, how many pieces can he cut from the big board?

Answer 1

13 pieces because 18 divided by one and one third is 13 and 1/2. Since you can have half a shelf, you have to take only the whole numbers.

Answer 2

18 ft* (1 piece/ 1 1/3 ft)= 13.5 pieces.

Mr. Gengel can only cut 13 pieces from the big board (because we don't have half a piece)~
