$\displaystyle \frac{ 16 + \frac{1}{2} }{ 81 + \frac{3}{4} }$

$\displaystyle = \frac{ \frac{33}{2} }{ \frac{327}{4} }$

$\displaystyle = \frac{33}{2} \times \frac{4}{327}$

$\displaystyle = \frac{33 \times 2}{327}$

$\displaystyle = \frac{66}{327}$

$\displaystyle = \frac{22}{109}$

------------

$\displaystyle \frac{ 12 ( a^{3} b^{2} c ) ^{4} }{ 4 ( a^{2} c^{6} ) }$

$\displaystyle = \frac{ 3( a^{12} b^8 c^4 ) }{ ( a^2c^6 ) }$

$\displaystyle = \frac{ 3 a^{10} b^2 }{ c^2 }$
