I'm having a tough time with the rules of simplifying radicals with fractions.

I don't understand why can't I reduce, $\displaystyle -\sqrt\frac{60}{5}$

to $\displaystyle -\sqrt\frac{12}{1}$

Skeeter if I have $\displaystyle -\frac{9}{2\sqrt45}$

Would the solution be:

$\displaystyle -\frac{9}{2\sqrt{3 \cdot 3 \cdot 5}}$

=

$\displaystyle -\frac{9}{2 \cdot 3 \sqrt5}$

=

$\displaystyle -\frac{9}{6\sqrt5}$

$\displaystyle -\frac{3}{2\sqrt5}$

$\displaystyle -\frac{3\sqrt5}{10}$
