    Hello,

    1/3-1/6=2/6-1/6=1/6

    2/5-1/3=../15-.../15

    We want to break this problem down. The first thing that we'll need to do is the subtractions.

    \frac{1}{3} - \frac{1}{6} = \frac{2}{6} - \frac{1}{6} = \frac{1}{6} so our numerator is \frac{1}{6}.

    \frac{2}{5} - \frac{1}{3} = \frac{6}{15} - \frac{5}{15} = \frac{1}{15} so our denominator is \frac{1}{15}.

    When we divide by a fraction, we multiply by its reciprocal, so we have \frac{1}{6} \cdot 15, which is \frac{5}{2}.

    you mean 15/2? because 5/2 is not a choice
