Question
Patrick used 42 centimetres of tape to wrap 7 presents. How many presents did Patrick wrap if he used 48 centimetres of tape? Solve using unit rates
Solution
Step 1: Find the unit rate. The unit rate is found by dividing the total amount of tape used by the total number of presents wrapped. In this case, Patrick used 42 centimetres of tape for 7 presents. So, 42 cm ÷ 7 presents = 6 cm/present. This means Patrick uses 6 centimetres of tape per present.
Step 2: Use the unit rate to find out how many presents Patrick wrapped if he used 48 centimetres of tape. To do this, divide the total amount of tape used by the unit rate. So, 48 cm ÷ 6 cm/present = 8 presents.
Therefore, Patrick wrapped 8 presents using 48 centimetres of tape.
