chelsea wants to build some birdhouses. she has a 12 foot board of wood. each birdhouse needs 3/4 foot of wood. how many birdhouses can chelsea build?
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 feet * (4/3) birdhouses/foot
12 feet * (4/3) birdhouses/foot = 48/3 birdhouses = 16 birdhouses
Chelsea can build 16 birdhouses.
