Question

what is 4 feet, 1 inch minus 2 feet, 11 inches?
A. 1 ft, 9 in
B. 2 ft, 2 in
C. 1 ft, 2 in
D. 2 ft, 4 in

Answer 1

I think the easiest way to approach this is to first convert them into inches. There are 12 inches in 1 foot, so the first value will be 49 inches and the second value is 35 inches. Subtract 49-35 which is 14 inches. Convert back to feet and you will get 1 foot 2 inches.
