Question

Adam is building birdhouses that require 1/2 -ft- long boards. How many pieces that are exactly 1/2 ft long can be made from a board that is 8 1/4 ft long? Show your work

Answer 1

16

Explanation:

Adam is building birdhouses that require
`(1)/(2) = 0.5` feet long exactly.

Now, we have a board of
`8(1)/(4) = (33)/(4) = 8.25` feet.

Now, we can write 8.25 = (16 × 0.5) + 0.25

Therefore, there can be a total 16 pieces that exactly 0.5 feet long can be made from the board that is 8.25 feet long and the remaining board will be of 0.25 feet. (Answer)
