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.
To convert the mixed number to an improper fraction, we multiply the whole number (10) by the denominator (5) and add the numerator (2). This gives us 10 2/5 = (10 * 5 + 2)/5 = 52/5.
The length of each birdhouse is 1 3/10 feet.
To convert the mixed number to an improper fraction, we multiply the whole number (1) by the denominator (10) and add the numerator (3). This gives us 1 3/10 = (1 * 10 + 3)/10 = 13/10.
Now we can divide the length of the board by the length of each birdhouse:
52/5 / 13/10 = 52/5 * 10/13 = (52 * 10) / (5 * 13) = 520/65 = 8
Therefore, 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) birdhouses
