Answer: 2' 3"
In other words, it's 2 feet, 3 inches
=================================================
Work Shown:
Convert the 4'1" to purely inches only
4'1" = 4 ft, 1 inch
4'1" = 4 ft + 1 inch
4'1" = 48 inches + 1 inch
4'1" = 49 inches
Note how 4 ft = 4*12 = 48 inches
-------------------
Through similar steps, you should find that 1'10", aka 1 ft 10 inches, is equivalent to 22 inches
Subtracting the two quantities gets us
(4' 1") - (1' 10") = (49 inches) - (22 inches) = 27 inches
Now convert that to the format "feet,inches".
27 in = 24 in + 3 in
27 in = (24/12 ft) + 3 in
27 in = 2 ft + 3 in
27 in = 2 ft, 3 in
27 in = 2' 3"
