Let's represent the population of Chicago as "x". We know that the population of New York City is about 9.9 million more than the population of Chicago. Therefore, we can create the equation:

18.8 million = x + 9.9 million

To solve for x, we can subtract 9.9 million from both sides of the equation:

18.8 million - 9.9 million = x

8.9 million = x

Therefore, the approximate population of Chicago is 8.9 million.
