    Show us how you keep getting 4/12 or 1/12. Can not correct bad behaviors, if we do not know what you are doing. I will say, that one of the answers you "keep getting", is the right answer; it just hasn't been reduced. Both show us both of your methods that lead you to 4/12 or 1/12.

    4/12=4/(3x4)=1/3

    (I agree with ANDS!, better to show what you have been suffering for)

    \frac{2}{3}\left(-\frac{1}{4}\right) + \frac{1}{2}

     = - \frac{2}{12} + \frac{6}{12}

     = \frac{4}{12}

     = \frac{4\cdot 1}{4\cdot 3}

     = \frac{1}{3}.
