Question

3. The population of Columbus, Ohio, in 2014 was about 823,000. The population of the United States was about 319 million in 2014.

(a) Write each population in scientific notation.
(b) About how many times larger was the population of the United States than the population of Columbus, Ohio? Show your work.

Answer 1

a.) Columbus Ohio Pop: 8.23 X
`10^(5)`
United States Pop: 3.19 X
`10^(8)`

b.) And to find about how many times larger the population of the U.S. is than Columbus, Ohio, I divided the U.S. pop by the Columbus pop and got the answer: 387.6.

So, the closest whole number would be 388 times larger.

Sorry for the rushed answer but the bell is about to ring for me to leave school :*D
