@pianoem328 Are there any common factors of 32 and 36?
OpenStudy (anonymous):
Um... I'm sorry I'm really bad at math. It might take me a while to figure this out.
OpenStudy (ash2326):
ok, take your time. Can you list out factors of 32?
OpenStudy (anonymous):
sure i'll try

I think the factors are 1, 2, 4, 8, 16, and 32.
OpenStudy (ash2326):
Very good piano, you're correct.
OpenStudy (ash2326):
Now list the factors of 36
OpenStudy (anonymous):
Alright
OpenStudy (anonymous):
I think they are 1, 2, 3, 4, 6, 9, 12, 18, and 36.

correct, now look for common factors between the factors of 32 and 36
OpenStudy (anonymous):
I think the common factors are 1, 2, and 4.
OpenStudy (ash2326):
We will choose the highest factor which is 4
OpenStudy (anonymous):
Okay.
OpenStudy (ash2326):
now, divide both 32 and 36 by 4
\[32:36=\frac{32}{4}:\frac{36}{4}\]

\[32\div4=8\]
OpenStudy (ash2326):
yes, do the same for 36
OpenStudy (anonymous):
\[36\div4=9\]
OpenStudy (anonymous):
Is that correct?
OpenStudy (ash2326):
yes, so we get
\[32:36=8:9\]

Thanks so much @ash2326
OpenStudy (ash2326):
piano did you understand?
OpenStudy (anonymous):
Yeah I did. I can do the rest of the test now :)
OpenStudy (ash2326):
piano are you taking a test right now?
OpenStudy (anonymous):
I just started it. That was a question on the lesson not the test.

I wanted to understand it good before I started the test.
OpenStudy (ash2326):
piano I'll take your word for now. But please don't ever use Open Study for help in your test, that would be cheating.
OpenStudy (anonymous):
Ik that's why I don't do it. Thanks for all the help ash :)
OpenStudy (ash2326):
yeah :)
