Given 9 yards of fabric

how many whole costumes could be made if each costume uses 1 3/7 yards of fabric

2 answers

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.
