A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.

Explanation:

You know that:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), knowing the values a, b and c and x being the unknown, we must apply the direct rule of three as follows:

a ⇒ b

c ⇒ x

So

To find the number of ounces a 19.45-inch length of the same string would weigh, you apply the following rules of three:

centimeters=49.403

grams= 933.34

ounces= 32.92

A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.
