How would I reduce this fraction?

$$\frac{km+kn}{n^2+nm}$$

I think it would be $\frac{2k}{n^2}$ but I am not sure.

    @Brett, that's not fair! Now everybody else's answers look worse.2012-06-07

    In general, blind speculation is not a very good problem solving method. Study the solutions well so that you remember a starting point next time (in this case, it was factoring.)2012-06-07

    In general, when reducing a fraction, factoring is your friend.2012-06-07

    Since "reducing" is "canceling factors", yes.2012-06-07

    Why did you think it was $\frac{2k}{n^2}$?2012-06-07

    @TonyK Sorry, the OP had half uppercase and half lowercase. Lowercase just looked better to me.2012-06-07
