Hasan has 18 3/4 yards of fabric. It takes 3 1/6 yards to make a pillowcase. Hasan plans to make as many pillow cases as he can. How many yards of fabric is left over?

I decided to simply both equations:

75/4 * 3 225/12

19/6 * 2 38/12

First is to find a common factor which is 12, multiply both sides.

divide 38/225 and you should get 5.92.

Hasan can make a total of 5 pillow cases.
