Population

3.1 * 10 ^ 8

3.38 * 10 ^ 7

12 * 10 ^ 8

About how many times larger was the population of the United States than Canada in 2011?

A 3.72 * 10 ^ 16

B 9.17 * 10 ^ 0

C 9 17 * 10 ^ 14

D 1.25 * 10 ^ 16

1 answer

B 9.17 * 10 ^ 0

To find the answer, we divide the population of the United States by the population of Canada:

(3.1 * 10^8) / (3.38 * 10^7)
= (3.1 / 3.38) * 10^(8-7)
= 0.917 * 10^1
= 9.17

So, the population of the United States was about 9.17 times larger than Canada in 2011.
