About how many times larger was the population of the United States than the population of Columbus,Ohio?show your work .....the population oh Columbus was 823,000 and United States was 319 million in suppose to use it in scientific notation to get the answer I have the answer for scientific notataion but I just don't know how to show how many times larger in scientific notation ..

OpenStudy (kelhina):

Im*

@madangerzone

OpenStudy (jackthegreatest):

319,000,000/823,000 = ...

OpenStudy (kelhina):

Don't I have to do it in scientific notation

OpenStudy (jackthegreatest):

yes, the answer is roughly 387.6

OpenStudy (jackthegreatest):

in scientific notation, 3.8 x 10^2

OpenStudy (kelhina):

Oh so I just put the answer in scientific notation I thought I had to like do it like this 3.19 *10^8 / 8.23*10^5

OpenStudy (kelhina):

?

OpenStudy (jackthegreatest):

sorry i was away, no you divide first, then you convert to scientific notation

OpenStudy (kelhina):

Are you sure?like 100 percent sure

OpenStudy (kelhina):

Because I know there's a way you can do it like that

OpenStudy (kelhina):

@jackthegreatest

OpenStudy (jackthegreatest):

the converting to scientific notation first also works

OpenStudy (kelhina):

Can you show me how I would do that I think I need to show my work like that

OpenStudy (kelhina):

If I don't show my work I won't get any points

OpenStudy (jackthegreatest):

|dw:1475209523879:dw|

OpenStudy (jackthegreatest):

you just divide it separately

OpenStudy (jackthegreatest):

|dw:1475209685297:dw|

OpenStudy (jackthegreatest):

do you get now? @kelhina

OpenStudy (kelhina):

what did you do on that second response ?I got confused after that

OpenStudy (jackthegreatest):

whats the second response

OpenStudy (kelhina):

|dw:1475209971443:dw|

OpenStudy (kelhina):

what did you do right there

OpenStudy (jackthegreatest):

ahh i divided 3.19/8.23

OpenStudy (jackthegreatest):

and i divided the 10^8/10^5

OpenStudy (kelhina):

oh okay i see now i get it now thank you!!!

OpenStudy (jackthegreatest):

yay! another person helped : )

OpenStudy (kelhina):

thank you so much really it means a lot

OpenStudy (jackthegreatest):

: ) my pleasure

OpenStudy (kelhina):

(;

OpenStudy (kelhina):

@jackthegreatest hey im sorry lol one more question how much greater would i say it was in a sentence

OpenStudy (jackthegreatest):

in scientific notation right?

OpenStudy (kelhina):

ugh honestly i dont even know i think in standard form

OpenStudy (kelhina):

but im not sure standard form seems more accurate

OpenStudy (jackthegreatest):

scientific: 3.8 x 10^2 regular: roughly 387 times

OpenStudy (kelhina):

so id start with United Sates population was ........ greater than Columbus,Ohio. What would go in the middle tho

OpenStudy (kelhina):

oh okay so just 387 times right?

OpenStudy (jackthegreatest):

yep

OpenStudy (kelhina):

alright thank you
