Sammie bought a [10 2/5] -foot long board to make birdhouses. If each birdhouse uses [1 3/10] feet, how many birdhouses can she make?(1 point)
To find out how many birdhouses Sammie can make, we need to divide the length of the board by the length of each birdhouse.
The length of the board is [10 2/5] feet, which can also be written as 10 + 2/5 = 10 + 2/5 = 10.4 feet.
The length of each birdhouse is [1 3/10] feet, which can also be written as 1 + 3/10 = 1 + 3/10 = 1.3 feet.
To find the number of birdhouses Sammie can make, we divide the length of the board by the length of each birdhouse:
10.4 feet ÷ 1.3 feet = 8.
Therefore, Sammie can make 8 birdhouses.
