Ruben used 9 centimeters of tape to wrap 3 presents. How many presents did Ruben wrap if he used 24 centimeters of tape? Assume the relationship is directly proportional.

Answer

Solution: Since the relationship is directly proportional, we can set up a proportion:

  1. 9 cm / 3 presents = 24 cm / x presents

Cross-multiply to solve for x:

9x = 24 * 3

9x = 72

x = 72 / 9

x = 8

Ruben wrapped 8 presents.
