OpenStudy (ash2326):

@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

OpenStudy (anonymous):

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.

OpenStudy (ash2326):

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 \[32:36=\frac{32}{4}:\frac{36}{4}\]

OpenStudy (anonymous):

\[32\div4=8\]

OpenStudy (ash2326):

yes, do the same for 36

OpenStudy (anonymous):

\[36\div4=9\]

OpenStudy (anonymous):

Is that correct?

OpenStudy (ash2326):

yes, so we get \[32:36=8:9\]

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

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 :)
