Answer

$\huge \frac{(\frac{a}{b})}{2}=\frac{a}{2b}$

Work Step by Step

Lets just ignore $\large\frac{a}{b}$ for now by calling it $x$. $\large \frac{\color{blue}{\large\frac{a}{b}}}{2}$ $\color{blue}{\large\frac{a}{b} = x}$ $\large\frac{\color{blue}{x}}{2} = \color{blue}{x} * \frac{1}{2} $ $\large \color{blue}{\large\frac{a}{b}} * \frac{1}{2} $ $\large \frac {(a*1)}{(b*2)}$ Our answer is: $\huge\frac{a}{2b}$
