And I'm terrible at this stuff..If someone wouldn't mind walking me through these, I'd be super grateful.

With this one, I know i need to add up the nominator and denominator by finding a common denominator for each..then to take:

[(t^2-s^2)/(s^(2)t^(2))]/[(t+s)/(st)]

But then I'm stuck.

Please and thanks!!

#1)What are you supposed to do here?

#2) Factor . You should get and you get some nice cancellation.

#3)Multiply the whole thing by (st)/(st)

Or notice you can apply the difference of squares formula to the numerator and notice that something cancels :

Much more elegant.
