Explanation

Setting up a simple proportion.

If the ration of Georgia to West Virginia was 9 to 2 o \(\frac{9}{2}\) and the population of West Virginia was 1.8 million, we do have:

\(\frac{1.8}{x} = \frac{2}{9}\)

Cross multiply and we do have \(\frac{1.8 * 9}{2} = 8.1\)

Georgia is in the E category. The answer D is correct
