Given 9 yards of fabric
how many whole costumes could be made if each costume uses 1 3/7 yards of fabric
1 3 / 7 = 7 / 7 + 3 / 7 = 10 / 7
9 / ( 10 / 7 ) = 9 * 7 / 10 = 63 /10 = 6.3
6 whole costumes could be made
Are these square yards of fabric? If not, you need the width of the fabric to come to an answer. If so, it needs to be indicated in your question.
To calculate the number of whole costumes that can be made from 9 yards of fabric, we need to divide the total length of the fabric by the length required for each costume.
First, let's convert 1 3/7 yards into an improper fraction. To do this, multiply the whole number (1) by the denominator (7) and add the result (7) to the numerator (3), giving us 10/7 yards.
Now we can divide the total length of fabric (9 yards) by the length required for each costume (10/7 yards):
9 ÷ (10/7) = 9 × (7/10) = 63/10
To determine the number of whole costumes, we divide the numerator (63) by the denominator (10) and round down to the nearest whole number:
63 ÷ 10 = 6.3
So, you can make a maximum of 6 whole costumes from 9 yards of fabric.
