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

anastassius [24]

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.

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

Hope this helps :)
