### Instruction: What fraction of $\frac{1}{2}$ is $\frac{1}{7}$?### Response: To find the fraction of $\frac{1}{2}$ that is $\frac{1}{7}$, I need to divide $\frac{1}{7}$ by $\frac{1}{2}$.
I can do this by multiplying $\frac{1}{7}$ by the reciprocal of $\frac{1}{2}$, which is 2.
So, $\frac{1}{7}$ divided by $\frac{1}{2}$ is the same as $\frac{1}{7}$ times 2, which is $\frac{2}{7}$.
Therefore, $\frac{2}{7}$ is the fraction of $\frac{1}{2}$ that is $\frac{1}{7}$.
