Question

As of May 2017, it was estimated that the population of the United States was 3.26 x 10 to the power of 8 and the population of the world was 7.5 x 10 to the power of 9 . To the nearest one-hundredth of a percent, what percentage of the world population was the United States population?

Answer 1

To find the percentage of the world population that the United States population represents, divide the United States population by the world population, and multiply the result by 100. The United States population is 3.26 x 10^8 and the world population is 7.5 x 10^9. Therefore, approximately 4.34% of the world population is represented by the population of the United States.

Step-by-step explanation:

To find the percentage of the world population that the United States population represents, divide the United States population by the world population, and multiply the result by 100. The United States population is 3.26 x 108 and the world population is 7.5 x 109.

Calculating:

(3.26 x 108) / (7.5 x 109) x 100 = 4.34%

So, approximately 4.34% of the world population is represented by the population of the United States.
