    I assume that is \[\frac{2x-4}{5x}\frac{15x}{x-2} \] right?

    You can rewrite that like this... \[\frac{2(x-2)}{5x}\frac{3(5x)}{x-2} \] which would be six, no?

    It's called LaTeX, don't worry about it. And just look at it, I dunno what else to tell you really. 2x-4 = 2(x-2), right?

    So, the (x-2)'s cancel, and the 5x's cancel, leaving you with 2*3 = 6.

    It's a document typesetting language called LaTeX. If you can't work the buttons don't worry about it because what I just typed looks like this: "\frac{5}{pq^2} \frac{-3p^3r}{10q} "

    I understood what you meant well enough when you just typed it.

    And to answer your question, that would be \[\frac{-15p^3r}{10pq^3} = \frac{-3p^2r}{2q^3}\]

    can you explain how you got that?

    I can tell you that when you multiply fractions, you multiply the numerators and denominators together, and that 15 and 10 share a common factor of 5 so that reduces to 3/2 when you cancel it, and p^3 / p = p^2, but besides that, I apologize, I do not know how to explain it further.
