Let's assume the population of Chicago is "x".

The population of New York City is 9.9 million more than the population of Chicago, so we can write the equation:

18.8 million = x + 9.9 million

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

18.8 million - 9.9 million = x

8.9 million = x

So, the approximate population of Chicago is 8.9 million.
