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 be written as an improper fraction:
10 2/5 = (10*5 + 2)/5 = 52/5
The length of each birdhouse is 1 3/10 feet which can be written as an improper fraction:
1 3/10 = (1*10 + 3)/10 = 13/10
To divide 52/5 by 13/10, we need to multiply the first fraction by the reciprocal of the second fraction:
(52/5) / (13/10) = (52/5) * (10/13) = (52*10) / (5*13) = 520/65 = 8
So, Sammie can make 8 birdhouses.
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)
