To solve the expression \( \frac{5}{7} - \frac{1}{2} \), we need to find a common denominator.

1. The denominators are 7 and 2. The least common denominator (LCD) of 7 and 2 is 14.
2. Rewrite both fractions with 14 as the denominator:

\[
\frac{5}{7} = \frac{10}{14}, \quad \frac{1}{2} = \frac{7}{14}
\]

3. Now subtract the fractions:

\[
\frac{10}{14} - \frac{7}{14} = \frac{3}{14}
\]

Thus, \( \frac{5}{7} - \frac{1}{2} = \frac{3}{14} \).
