Question

Lucy used 1 1/8 yards of cloth to make a dress. How many dresses can she make in 10 yards of cloth? How many yards of cloth will remain unused?

​

Answer 1

Answer: 8 dresses, with 8 yards remaining.

Explanation:
1 1/8 can be rewritten as the improper fraction 9/8 and 10 can be converted to the improper fraction 80/8. Dividing 80/8 by 9/8, the 8’s in the denominators of each fraction cancel, leaving 80 divided by 9, which goes in evenly 8 times with a remainder of 8.
