Algebra

this should be correct if not just let me know. hope this helps.

$\sqrt{\frac{3}{5}}=\frac{\sqrt{3}}{\sqrt{5}}$

$\frac{\sqrt{3}}{\sqrt{5}}=\frac{\sqrt{3}}{\sqrt{5}}*\frac{\sqrt{5}}{\sqrt{5}}$

$\frac{\sqrt{3}}{\sqrt{5}}*\frac{\sqrt{5}}{\sqrt{5}}=\frac{\sqrt{3*5}}{\sqrt{5*5}}$

$\frac{\sqrt{3*5}}{\sqrt{5*5}}=\frac{\sqrt{15}}{\sqrt{25}}$

$\frac{\sqrt{15}}{\sqrt{25}}=\frac{\sqrt{15}}{5}$
