$\frac{\sqrt a b}{b}$
$\frac{a \sqrt b}{b \sqrt a}$ We need to rationalize the denominator by multiply it by $\sqrt a$ because we cannot have a radical in the denominator $\frac{a \sqrt b}{b \sqrt a} \times \frac{\sqrt a}{\sqrt a}$ We multiply the radicals and bring them under one radical $\frac{a \sqrt a b}{ba}$ The a in the numerator cancels out the a in the denominator. $\frac{\sqrt a b}{b}$
