Question

Dan is cutting 4.75 foot lengths of twine from a 240 feet spool of twine. he needs to cut 42 lengths, and says that 40.5 feet of twine will remain. show that this is reasonable

Answer 1

Well if you do 4.75 ft times 42, you get 199.5ft. Then subtract 199.5 ft from 240ft and you end up with 40.5 left over. Yes, this is reasonable.
