    Here are some fractions to consider involving the number 9

    $\displaystyle \frac{1}{9} = 0.\dot{1}$

    $\displaystyle \frac{2}{9} = 0.\dot{2}$

    $\displaystyle \frac{3}{9} = 0.\dot{3}$

    and so on

    Yeah, it's a good idea to memorize the fraction/decimal/percents.

    $\displaystyle 1/2 = 50\%$

    $\displaystyle 1/3 = 33.\overline{3}\%$
    $\displaystyle 2/3 = 66.\overline{6}\%$

    $\displaystyle 1/4 = 25\%$
    $\displaystyle 2/4 = 1/2$
    $\displaystyle 3/4 = 75\%$

    $\displaystyle 1/5 = 20\%$
    $\displaystyle 2/5 = 40\%$
    $\displaystyle 3/5 = 60\%$
    $\displaystyle 4/5 = 80\%$

    $\displaystyle 1/6 = 16.\overline{6}\%$
    $\displaystyle 2/6 = 1/3$
    $\displaystyle 3/6 = 1/2$
    $\displaystyle 4/6 = 2/3$
    $\displaystyle 5/6 = 83.\overline{3}\%$

    $\displaystyle 1/7 = 14.\overline{285714}\%$
    ...
    (I wouldn't bother with these)

    $\displaystyle 1/8 = 12.5\%$
    $\displaystyle 2/8 = 1/4$
    $\displaystyle 3/8 = 37.5\%$
    $\displaystyle 4/8 = 1/2$
    $\displaystyle 5/8 = 62.5\%$
    $\displaystyle 6/8 = 3/4$
    $\displaystyle 7/8 = 87.5\%$

    Pickslides already showed 1/9, 2/9...

    $\displaystyle 1/10 = 10\%$
    ...
