    You can do this 2 ways: 1. convert both measurements to inches and just subtract 2. keep the measurements in ft and in. and borrow

    5ft = 60 in. 60 + 3 = 63in. 8ft = 96in. 96 + 2 = 98in. 98 - 63 = ?

    Since we can't subtract 3 inches from 2 inches, we borrow a foot from 8 ft. A foot is 12 inches, so we take 1 foot from 8 ft, and we add 12 inches to 2 inches. |dw:1439247949332:dw|
