Question

Justin used 42 centimeters of tape to wrap 14 presents. How many presents did Justin wrap if

he used 45 centimeters of tape? Solve using unit rates.

__ presents

Answer 1

15 presents

Explanation:

Since we are using unit rate, we have to find out how many centimeters he uses for 1 present. Therefore 42÷14=3 So he uses 3 centimeters of paper for 1 present. Since he used 45 centimeters of paper we divide that by 3 to see how many presents is in 45 centimeters. When dividing the answer is 15. Therefore he wraps 15 presents

Answer 2

15 presents

Explanation:

42 cm / 14 presents = 3 cm / 1

3cm / 1 presents = 45 / 15
