What is the sum of 6 feet and 10 inches and 8 feet and 9 inches?

Answer 1

There are two ways to do it. One way is to add the whole number units and then the partial units. 6 feet + 8 feet = 14 feet partial total 10 in + 9 in = 19 in 19/12 = 1.58333 feet partial total [1 whole unit ft and .583333*12 in = 7 in] therefore, 14 ft + 1 ft + 7 in = 15 ft 7 in Another way is to convert to inches to add, then break down into feet. (6 ft *12) + 10 in + (8 ft*12) + 9 in 72 + 10 + 96 + 9 = 187 in 187 / 12 = 15.58333 = 15 ft 7 in [15 whole unit ft and .583333*12 in = 7 in]
