    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 :o:

    Dividing one fraction by another? Turn the second fraction upside down and multiply.

    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
