Answer 1

Answer:

$\frac{11}{20}$

Step-by-step explanation:

Let x is the total population of the world.

Therefore, by the condition given the population of North America is $\frac{2x}{25}$

Again it is given that $\frac{11}{250}$ fraction of the world's population lives in the United States of America.  

So, $\frac{11x}{250}$ is the population of USA.

Therefore, the fraction of the population of North America that is the population of USA will be $\frac{\frac{11x}{250} }{\frac{2x}{25} } =\frac{11}{20}$ (Answer)
