Answer 1

C. ½ of an inch per foot

Explanation:

Given that
`(1)/(4) in.` represents
`(1)/(2) ft`.

Unit rate in inches per foot =
`(1)/(4) in. / (1)/(2) ft`

Change the division operation to multiplication, and flip the fraction on your right upside down.

Thus:

`= (1)/(4) * (2)/(1)`

Simplify

`= (1 * 2)/(4 * 1)`

`= (2)/(4) = (1)/(2)`

Unit rate in inches per foot = ½ of an inch per foot.
