Answer 1

To find out how many birdhouses Chelsea can build, we need to divide the length of the board of wood by the length of wood needed for each birdhouse.

12 feet / 3/4 foot/birdhouse = 12 * (4/3) = 12 * 4/3 = 48/3 = 16 birdhouses.

So, Chelsea can build 16 birdhouses. The correct answer is D. 16 birdhouses.
