    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
