HELPP!!!!!!!!

Martin is sewing costumes for the school play. He needs 1/3
yard of ribbon for each costume. He has 12 3/4 yards of
ribbon left. How many costumes can he finish making?

Answer 1

Answer:

simple convert to improper to subtract

51/4 turn to a common denominator

so multiply by 3

153/12. 4/12

then just divide 153 by 12 = 12.75* 3 bc 3 costumes are one yard and you get 38.25 costumes or 38 bc you cant have .25 of a costume
