To make shelves for a bookcase, Nate needs 7 pieces of lumber, each 45 inches long. Nate has several 10-foot lengths of lumber in the width and thickness he needs. How many of these 10-foot boards will Nate use?
Answered by Ms. Sue
Each piece of 10-foot-long lumber has 120 inches (12*10).

You need to figure how many times 45 goes into 120 to find the number of shelves Nate can get from each 10-foot long piece.

If you post your answer and the number of 10-foot boards Nate will use, we'll be glad to check it.

45 goes into 120 2 times.
Answered by Ms. Sue
Right. He can get 2 shelves out of each 10-foot board.

Since he needs 7 shelves, how many pieces of lumber does he need?
Answered by Mary
about 4
Answered by Ms. Sue
