4.13% of US population lives in Illinois.

Explanation:

In order to know the percent of the US population living in Illinois, we have to the following crossed multiplication:

307,000,000 = 100

12,700,000 = X

X = (12,700,000 . 100) / 307,000,000

X = 1,270,000,000 / 307,000,000

X =  4.13

As we can see, 4.13% of US population lives in Illinois.
