To rationalize the denominator of the expression \(\frac{\sqrt{7}}{\sqrt{11}}\), we can multiply both the numerator and the denominator by \(\sqrt{11}\):
\[ \frac{\sqrt{7}}{\sqrt{11}} \cdot \frac{\sqrt{11}}{\sqrt{11}} = \frac{\sqrt{7} \cdot \sqrt{11}}{\sqrt{11} \cdot \sqrt{11}} \]
This simplifies to:
\[ \frac{\sqrt{77}}{11} \]
Thus, the final simplified answer is:
\[ \frac{\sqrt{77}}{11} \]
