Question

In a parking lot of 240 red and blue cars, the ratio of red cars to blue is 3:5

How many red cars are there?

Answer 1

There would be 144 red cars.

Explanation:

3:5 is equal to 3/5

240 * (3/5) = 144

Answer 2

90 red cars

Explanation:

sum the parts of the ratio 3 + 5 = 8 parts

divide 240 by 8 to find one part of the ratio

240 ÷ 8 = 30 ← 1 part of the ratio

3 parts = 3 × 30 = 90 ← number of red cars

5 parts = 5 × 30 = 150 ← number of blue cars
