Your answer is $\frac{2}{35}$.

Explanation:

$\frac{1}{7} \div \frac{5}{2}$, firstly to solve this you have to change the sign to multiplication and to do that you must switch the numerator and denominator of the second which is $\frac{5}{2}$ so it becomes $\frac{2}{5}$ then you start solving so it is $\frac{1}{7} \cdot \frac{2}{5}$ that is $\frac{2}{35}$
