Question

Unit Rate and Constant of Proportionality

Answer 1

Answer:

C. ½ of an inch per foot

Step-by-step explanation:

Given that $\frac{1}{4} in.$ represents $\frac{1}{2} ft$.

Unit rate in inches per foot = $\frac{1}{4} in. \div \frac{1}{2} ft$

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

Thus:

$= \frac{1}{4} \times \frac{2}{1}$

Simplify

$= \frac{1 \times 2}{4 \times 1}$

$= \frac{2}{4} = \frac{1}{2}$

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