Jose purchased 5.5 feet of rope to hang a planter on the back porch. the planter required a set of 3 ropes measuring 18 inches each. after jose cuts the rope and hangs the planter, how much rope will he have left?

You have to multiply 18 by three which is 54 inches.
then you have to divide 54 by 12 because a foot is 12 inches.
when you do that you should get 4.5
then you subtract 4.5 by 5.5 and get 1 foot of rope left
18*3=54
54/12=4.5
5.5-4.5=1.0
1 foot of rope
