Write the following as a single fraction?

OpenStudy (anonymous):

@cshalvey ?

@MarkRijckenberg

OpenStudy (anonymous):

How complicated is this supposed to be? Are there any other questions to compare this to?

OpenStudy (anonymous):

The question before it was 4/x + x/y

OpenStudy (anonymous):

Was the answer to that 4y+x^2/xy ?

OpenStudy (anonymous):

Yes! And it took a viddy long while to work out!

OpenStudy (anonymous):

For the original question, we're going to focus on the first 2 terms. Multiply 1/a by b, and 1/b by a

OpenStudy (anonymous):

so 1b/ab and 1a/ab?

OpenStudy (anonymous):

yes, and when you combine those two terms, it come out to b-a/ab.

OpenStudy (anonymous):

Yes it does thankyou. And then is there another part?

OpenStudy (anonymous):

Yes, now multiply b-a/ab by c, and 1/c by ab

OpenStudy (anonymous):

cb-a/abc and 1ab/abc?

OpenStudy (anonymous):

The first term should have bc-ac in the numerator, but everything else is fine.

OpenStudy (anonymous):

Oh yeah! I only timed b by c and not a by c. So now I need to make them two into the one fraction. Do I add them?

OpenStudy (anonymous):

Yes.

OpenStudy (anonymous):

What is bc-ac plus 1ab?

OpenStudy (anonymous):

1ab+bc-ac?

OpenStudy (anonymous):

all over abc

OpenStudy (anonymous):

Yay!

OpenStudy (anonymous):

That was like the most I have ever learned. Do you teach?

OpenStudy (anonymous):

Nope, college student.

OpenStudy (anonymous):

NO WAY. DA FUQ!

OpenStudy (anonymous):

Well youre better than any maths teacher I've ever had!

OpenStudy (anonymous):

Ok thank you! :)
