To compute the product of \( \frac{1}{2} \cdot \frac{5}{7} \):
\[ \frac{1}{2} \cdot \frac{5}{7} = \frac{1 \cdot 5}{2 \cdot 7} = \frac{5}{14} \]
Next, we need to compare \( \frac{5}{14} \) with \( \frac{1}{2} \).
To compare these fractions, we can convert \( \frac{1}{2} \) to a fraction with a denominator of 14:
\[ \frac{1}{2} = \frac{1 \cdot 7}{2 \cdot 7} = \frac{7}{14} \]
Now we compare \( \frac{5}{14} \) and \( \frac{7}{14} \):
Since \( 5 < 7 \), we find that:
\[ \frac{5}{14} < \frac{7}{14} \]
Thus, we can complete the comparison statement:
\[ \frac{1}{2} \cdot \frac{5}{7} < \frac{1}{2} \]
The answer is \( < \).
