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

Answer:

  7.5 times

Step-by-step explanation:

Your calculator can tell you the ratio ...

  $\dfrac{3\times10^8}{4\times10^7}=\dfrac{30\times10^7}{4\times10^7}=\dfrac{30}{4}=\boxed{7.5}$

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