Question

a carpenter needs to buy either an 8 foot or a 10 foot piece of wood that will be cut into three pieces. these pieces will be 4 3/4 feet, 1 5/6, and 2 2/3 feet long. what length of wood should the carpenter buy?

Answer 1

well, what is the total length of the pieces?

4 3/4 + 1 5/6 + 2 2/3
= 4+1+2 + 9/12 + 10/12 + 8/12
= 7 + 27/12
= 7 + 2 3/12
= 9 1/4 ft

Answer 4

What about part b: Later, the carpenter needs to go back to the lumber store for more lumber. He will cut 3 more pieces the same size as 9 3/12ft. In addition, he will cut a piece that is 3 3/4 feet long. The carpenter thinks he needs a 12-foot piece of lumber. Do you agree or disagree? Support your answer using information from the problem.
