Mr. Blanco used 15.75 yards of fabric to make 7 costumes for the school play. How many yards of fabric did he use per costume?

2.25 yards per costume

Step-by-step explanation:

if you want to find the unit rate of something put it into a fraction which is also considered dividing. Like if you want to figure out miles per hour or ounces per cup, just divide miles by hour, or divide ounces per cup to get your final answer. In this case divide 15.75 yards of fabric by 7 costumes to get your answer.
