Answer 2

The percent of the world's population lives in North America is 5%.

Explanation:

Given:

Of the 6.25 billion people in the world, 310 million live in North America.

Now, to find the percent of the world's population lives in North America.

Population of people in the world = 6.25 billion.

1 billion = 1000 million.

So, by using conversion factor we convert into million:

6.25 billion = 6250 million.

Population of people in North America = 310 million.

Now, to get the percent of the world's population lives in North America:

`(310)/(6250) * 100`

`=0.0496* 100`

`=4.96\%.`

So, the percent to the nearest whole number is 5%.

Therefore, the percent of the world's population lives in North America is 5%.
