Applying Ratios and Rates
Challenge
A parking lot has three sections. The ratio of the number of cars in the first section to the number
of cars in the second section to the number of cars in the third section is 1 : 2 : 3. There are 36
cars in all three sections of the parking lot.
1. How many cars are in each section of the parking lot?

2. What is one way in which you can move some of the cars between sections so the ratio of cars
between sections of the parking lot is 1 : 1 : 1?

3. Another parking lot with three sections has 80 cars in it. Is it possible for ratio of the number of
cars in the first section to the number of cars in the second section to the number of cars in the
third section to be 1 : 2 : 3? Explain why or why not.

4. Suppose 18 cars are added to the original parking lot of 36 cars in which the ratio of the
number cars in the first section to the number of cars in the second section to the number of cars
in the third section is 1 : 2 : 3. If all 18 cars are placed in the third section, what will be the new
ratio of the number of cars in each section?
