Mark Nguyen is a tailor making costumes for a play.He needs enough material for 1 large shirt that requires 11/2 yards of material and 5 small shirts that each require 3/4 yard of material. he finds a 5 yard remnant of material on sale is 5 yards of material enough to make all 6 shirts? if not how much more material does he need?

Answer :

So he needs 6 shirts total, (5×(3/4))+(1×(11/2))
so basically (15/4)+(11/2)
to add these, get a common denominator and you'll get your answer...
