Question

About 2/25 Of the population of the world lives in North America.Of the population of the world lives in North America It's about 11/250 of the population of the world lives in United States of America what fraction of the population of North America lives in USA?

Answer 1

`(11)/(20)`

Explanation:

Let x is the total population of the world.

Therefore, by the condition given the population of North America is
`(2x)/(25)`

Again it is given that
`(11)/(250)` fraction of the world's population lives in the United States of America.

So,
`(11x)/(250)` is the population of USA.

Therefore, the fraction of the population of North America that is the population of USA will be
`((11x)/(250) )/((2x)/(25) ) =(11)/(20)` (Answer)
