During World War I, 116,516 US soldiers were killed and 204,002 were wounded. If you add those two numbers together, the total number of US soldiers killed or wounded was 320,518.
You can represent that as a fraction of the current population of Chicago like this:

For simplicity's sake (since I assume the Chicago population number is an estimate), let's round the number of soldiers killed or wounded down to 300,000. That would look like this:

We can simplify that down a lot by dividing the number of soldiers and the number of Chicagoans by the least common denominator of 300,000. That would give us this fraction:

So for every 1 US soldier killed or wounded in World War I, there are 10 Chicagoans living in the city today.

Answer:
Ancient civilizations based a large part of their economy and their subsistence on trade and exchange of goods. Thus, they were guided by a very simple premise: they traded what they had left over, to obtain in exchange what they lacked. For example, if a civilization overproduced wheat, it could trade that surplus for goods it did not have, such as animals. In this way, all civilizations covered their needs without the obligation to procure them all by their own hand.
