The ratio of blue to red cars in the parking lot is 3 to 5. If there were 60 red cars how many blue cars would there be?

A.50
B.40
C.38
D.36
How do you solve it

A:50

Harley is incorrect.

Set up a proportion, cross multiply, and solve for x.

3/5 = x/60

5x = 180

x = 36

Thank you Ms.Sue

You're welcome, Jerald.

To solve this problem, you need to use the given ratio and the number of red cars to find the number of blue cars.

Given that the ratio of blue to red cars is 3 to 5, this means that for every 3 blue cars, there are 5 red cars.

Since you're given that there are 60 red cars, you can set up a proportion to find the number of blue cars.

Let's assign a variable, "x," to represent the number of blue cars.

So, the proportion is:

3 blue cars / 5 red cars = x blue cars / 60 red cars

To find the value of x, you can cross-multiply and solve for x:

3 * 60 = 5 * x

180 = 5x

Dividing both sides by 5 gives:

x = 36

Therefore, there would be 36 blue cars in the parking lot.

The correct answer is D. 36.
