Question

11. In a parking garage there is a 6:5 ratio of blue cars to

red cars. If there are 275 cars in the garage, how many
red cars are in the garage?

Answer 1

Answer: 125 Red Cars

6:5 = 275; Write as equation by adding a variable to the ratio:

6x + 5x = 275; add
11x = 275; divide
x = 25; put 25 in for “5x,” which represents the ratio 5 for red cars

5(x) = 5(25) = 125

Check:
6(25) + 5(25) = 275; multiply
150 + 125 = 275; add
275 = 275; is true so answer is right.
