Benjamin is making bow ties. how many 1/2 yard long bow ties can he make if he has 18 feet of fabric

Marizza181 [45]

I estimate he can make around 12 such bowties, this is based off a year being 3 feet and therefore half a yard is 1 1/2 feet. So 12x 1 1/2= 12 12/2=6+12=18 all the fabric is used up.
