The PRP and PRF have a special relationship called ______.

The PRP and PRF have a special relationship called ______.

• A. Inverse
• B. Direct
• C. Reciprocal
• D. Linear

Answer: (C)

Reciprocal relationships describe two quantities that are inverse of each other, so their product is 1. For PRP and PRF, this means PRP × PRF = 1, or PRF = 1/PRP. The idea is that as one value grows, the other gets smaller in just the right way to keep their product at 1. Nonzero values are essential because zero has no reciprocal. For example, if PRP is 2, PRF is 1/2; if PRP is 0.25, PRF is 4. This precise inverse relationship is different from a direct or linear relationship, where the two quantities move together or change at a constant rate.
