60 ounces.

Step-by-step explanation:

A chain weighs 9 pounds per foot.

We are to find the number of ounces 5 inches weigh.

First we find how many feet are in 5 inches.

1 foot = 12 inches

how many feet? = 5 inches.

Cross-multiplying gives;

$\frac{5}{12} * 1 = \frac{5}{12}$ feet

1 foot of the chain = 9 pounds

$\frac{5}{12}$ feet = how many pounds?

Cross-multiplying gives;

$\frac{5}{12} * 9 = 3.75$ pounds

1 pound = 16 ounces

3.75 pounds = how many ounces?

Cross-multiplying gives;

$\frac{3.75 * 16}{1} = 60$ ounces.
