How do you simplify sqrt(11/132)?

$\sqrt{\frac{11}{132}} = \sqrt{\frac{11}{11 \cdot 12}} = \sqrt{\frac{\cancel{11}}{\cancel{11} \cdot 12}} = \sqrt{\frac{1}{12}} = \frac{1}{\sqrt{12}} = \frac{1}{2 \sqrt{3}} = \frac{\sqrt{3}}{2 \cdot \sqrt{3} \cdot \sqrt{3}} = \frac{\sqrt{3}}{2 \cdot 3} = \frac{\sqrt{3}}{6}$
