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.
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?
about 4
You're right. :-) Nate needs 4 pieces of board to make his shelves.
Slight correction -- Nate needs four 10-foot long boards to make 7 shelves.
so the answer is 4. thanx!!! ur a big help!! went through it step by step.
