Angie has 12 3/4 yards of fabric to make Halloween costumes. Each fabric costume requires 7/8 yards of fabric. How many costumes can Auntie make?​

Since Angie has 12 3/4 yards of fabric and all and each costume requires 7/8 yards, you can divide 12 3/4 by 7/8.

12 3/4 ÷ 7/8

= 51/4 ÷ 7/8

= 51/4 • 8/7 (remember that dividing by a fraction is the same thing as multiplying by it’s reciprocal)

= 51/1 • 2/7 (after simplifying)

= 102/7

= 14 4/7

Angie can make 14 costumes. She cannot make the 15th one because she’ll run short of fabric.
