\begin{array}{rcl} \genfrac{}{}{1pt}{0}{\frac{55qrt}{12x^2}}{-\frac{121x^5}{9q^2}} &=& \dfrac{55qrt}{12x^2} : \left(-\dfrac{121x^5}{9q^2}\right) \\\\ &=& \dfrac{55qrt}{12x^2} \cdot \left(-\dfrac{9q^2}{121x^5}\right) \\\\ &=& \dfrac{5qrt}{4x^2} \cdot \left(-\dfrac{3q^2}{11x^5}\right) \\\\ &=& -\dfrac{15q^3 rt}{44x^7} \end{array}
