### Eureka Math Grade 6 Module 1 Lesson 5 Example Answer Key

Example 1.
A County Superintendent of Highways is interested in the numbers of different types of vehicles that regularly travel within his county. In the month of August, a total of 192 registrations were purchased for passenger cars and pickup trucks at the local Department of Motor Vehicles (DMV). The DMV reported that in the month of August, for every 5 passenger cars registered, there were 7 pickup trucks registered. How many of each type of vehicle were registered in the county in the month of August?
a. Using the information in the problem, write four different ratios and describe the meaning of each.
The ratio of cors to trucks is 5: 7 and is a part-to-part ratio. The ratio of trucks to cors is 7:5, and that is a
part-to-part ratio. The ratio of cars to total vehicles is 5 to 12, and that is a part-to-whole ratio. The ratio of
trucks to total vehicles is 7 to 12, and that is a part-to-whole ratio.

b. Make a tape diagram that represents the quantities in the part-to-part ratios that you wrote.

c. How many equal-sized parts does the tape diagram consist of?
12

d. What total quantity does the tape diagram represent?
192 vehicles

e. What value does each individual part of the tape diagram represent?
Divide the total quantity into 12 equal-sized parts:
$$\frac{192}{12}$$ = 16

f. How many of each type of vehicle were registered in August?
5 . 16 = 80 passenger cars
7 . 16 = 112 pickup trucks

Example 2.
The Superintendent of Highways is further interested in the numbers of commercial vehicles that frequently use the countyâ€™s highways. He obtains information from the Department of Motor Vehicles for the month of September and finds that for every 14 non-commercial vehicles, there were 5 commercial vehicles. If there were 108 more non commercial vehicles than commercial vehicles, how many of each type of vehicle frequently use the countyâ€™s highways during the month of September?
