Question

What id the sum of 2'8" + 1'6"

Answer 1

Interesting question about feet and inches.  The best way to solve this problem is to ask yourself how many inches are in a foot.  Since there are 12 inches in every foot then the length of 2'8" can be written as (2*12)" + 8".  Which is 24+8 or 32 inches.  The second number (1'6") can be written as (1*12)"+6" which is 18 inches.  32 + 18 = 50 inches.  Or, if you want to change this back into feet and inches just divide it by 12.  50/12 is 4 R. 2.  So 4'2".
