In a parking lot of 240 red and blue cars, the ratio of red cars to blue cars is 3 : 5 how many red cars are in the parking lot?

Step-by-step explanation:

Given:

240 red and blue cars

3:5 ratio of red cars to blue cars

3 + 5 = 8

red cars: 3/8 * 240 = 90

blue cars: 5/8 * 240 = 150

ratio of red cars to blue cars: 90:150

simplify:

 90 ÷ 30 = 3

150 ÷ 30 = 5 

Thus: 90:150 = 3:5

Imagine math : 90, because 38 of the cars are red
