Malik used 27 centimeters of tape to wrap 9 presents. How many presents did Malik wrap if he used 42 centimeters of tape? Assume the relationship is directly proportional.

presents

1 answer

Let us set up a proportion to solve the problem:

27 centimeters of tape / 9 presents = 42 centimeters of tape / X presents

Cross-multiplying, we get:

27 centimeters of tape * X presents = 9 presents * 42 centimeters of tape

Simplifying, we have:

27X = 378

To solve for X, divide both sides of the equation by 27:

X = 378 / 27 = 14

Therefore, Malik wrapped 14 presents.
