Question

California, the most populous state, has approximately 4 x 107 people living in it. The population of the entire United States is approximately 3 x 108 people. How many times greater is the population of the United States than the population of California?

Answer 1

7.5 times

Explanation:

Your calculator can tell you the ratio ...

`(3*10^8)/(4*10^7)=(30*10^7)/(4*10^7)=(30)/(4)=\boxed{7.5}`

The population of the US is 7.5 times as great as the population of California.
