Question

Owen has 12 pieces of rope that are 4 yards each. Owen uses 6 pieces of rope that are each 6 feet long.How many feet of rope does Owen have left?

Answer 1

8×4=32ft
4×4=16ft

32-16=16ft

Answer 2

Hey there! 

If Owen has 12 pieces of rope that are 4 yards long each, or 12 feet long (a yard is three feet in length), he has 144 feet of rope total. If he uses 6 pieces of rope that are 6 feet long, he has used 3 pieces of his 12 foot long rope pieces, since 6*6 and 3*12 are both equal to 36 feet of used rope. 

All you need to do is subtract that 36 feet from the total of 144 feet to get 108 feet remaining. 

Hope this helped you out! :-)
