     \frac{30}{5}=6

    \frac{4}{5}\cdot \frac{6}{6}=\frac{24}{30}


    You want to multiply five so you can get 30, so divide 30 by 5 to find that number and then multiply the numerator and denominator by this number (because they cancle each other out in the long run leaving 1).

    sorry, i read the question too fast before.

    39/13=3

    (4/13)(3/3)=12/39
