so divide it by 5 to get the average
25 ft. 5 in./5=5 ft. 1 in.
hartnn (hartnn):
24 feet 17 inch divided by 5
24 + 1 feet, 5 inch divided by 5
=5 feet 1 inch
OpenStudy (mayankdevnani):

OpenStudy (anonymous):
yup @hartnn
hartnn (hartnn):
now 17 inch means 12 inch + 5 inch
and 12 inch = 1 feet
so 17 inch = 1 feet and 5 inch
