How tall is 91 inches in feet and inches?

Answer 1

Conversion Factors:1 foot = 12 inches

First multiply 91 inches by the conversion factor as a fraction ( in such a way where inches cancel out)

( 91 inches ) x ( 1 foot / 12 inches ) = 91/12 feet

Figure out the quotient (whole number) of 91/12:

91/12 feet ~= 7.58333 ft

So the quotient is 7 feet

Subtract 7 from 91/12 to get how many remaining inches there are in exact terms. (This is called your remainder)

91/12 - 7 = 91/12 - [ (7 x 12) / ( 12 ) ] = 91/12 - 84/12 = 7/12 feet

If you aren't able to see the remaining inches, use your conversion factor again, to convert feet to inches (the more you do this, the more you can skip this step).

( 7 feet / 12 ) x ( 12 inches / 1 foot ) = 7 inches.

The answer is your quotient + your remainder.

7 feet + 7 inches

Therefore 91 inches is equal to 7 feet 7 inches.
