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

15 presents

Step-by-step explanation:

42 cm / 14 presents = 3 cm / 1

3cm / 1 presents = 45 / 15

15 presents

Step-by-step 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
