Unit Rate and Constant of Proportionality

Mathematics

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.
