Hello,

$\displaystyle 1/3-1/6=2/6-1/6=1/6$

$\displaystyle 2/5-1/3=../15-.../15$

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

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

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

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

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

The solution is 5/2... None of the ones you gave :/
