Question

9. A new parking lot has spaces for 450 cars. The ratio of spaces for full- sized cars to compact cars is 11 to 4. How many spaces are for full-sized cars? How many spaces are for compact cars?

Answer 1

Answer:

330

Step-by-step explanation:

Ratio for full sized cars to compact cars = 11:4

Let common factor in ratio be 'x'.

       = 11x:4x

       = 11x + 4x = 450

       = 15x = 450

       = x = 450/15

       = x = 30

11x = 11 x 30

     = 330

4x = 4 x 30

    = 120

Verification = 330 + 120

                    = 450
