Question

What is the result of converting 81 inches to feet? Remember, these are 21 inches in a foot.

Answer 1

6.75 feet

Explanation:

We have to convert 81 inches to feet.

We can use unity method to solve this problem.

12 inches = 1 feet (Note that 12 inches make a foot not 21)

Dividing both sides by 12, we get:

1 inch =
`(1)/(12)` feet

Multiplying both sides by 81, we get:

81 inches =
`(81)/(12)` feet

81 inches =
`(27)/(4)` feet

81 inches = 6.75 feet
