What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

In the grids, there are 12 square box.

Let R be the red and B be the blue.

R + B = 12   ...1

R / B = 1/2  ...2

By solving equation 1 and 2, we have

R + 2R = 12

      3R = 12

        R = 4

Then  

4 + B = 12

     B = 8

Then the correct option is C.
