Question

which is a better estimate for the weight of a tennis racquet? 9 pounds 9 ounces

Explanation:

Step1: Consider real - life weight

A tennis racket is relatively light. 9 pounds is a very heavy weight for a tennis racket. 1 pound = 16 ounces, and 9 pounds = 9×16 = 144 ounces, which is much too heavy.

Step2: Analyze the other option

9 ounces is a more reasonable weight for a tennis racket as it is light enough to be easily maneuvered during play.

Answer:

9 ounces
