Question

Convert 9ft -2 1/2in to inches

Answer 1

NO THE FIRST ANSWERS WRONG
9 foot = 9*12 = 108 inches minus 2.5 inches would return the answer 105.5 inches

Answer 2

we know that

`1` ft is equal to
`12` in

so

`9` ft is equal to

by proportion

`(1)/(12) =(9)/(x) \\ \\ x=12*9\\ \\ x=108` in

therefore

`9ft-2(1)/(2) in=108 in-2.5 in\\ \\ =105.5 in`

`105.5 in=105 (1)/(2)in`

the answer is

`105 (1)/(2)in`
