# When you have "layers" of fractions? (A level) watch

1. Hi,

This has always baffled me and a calculator has been a useful companion so far but..... now I need to face this gremlin.

For example lets have:

p / q

If p is x-1/x+2
and q is x -2 / x+1

how on earth do you organise that?!

(I picked the numbers randomly, I just want to know how to arrange that in 2 lines)

I hope you get what I'm on about
2. Dividing one fraction by another? Turn the second fraction upside down and multiply.
3. Yes that is equivalent to x-1/x+2 X x-2/x+1

So you'd get (x-1)(x-2)/(x+2)(x+1)

Though i have to say, if i ever got that in a fraction i would probably cry lol
:P
