$\frac{12xa}{15ya} = \frac{12x}{15y} = \frac{4x}{5y}$

$\frac{12cb^{2}}{9bc^{3}} = \frac{12cb}{9c^{3}} = \frac{12b}{9c^{2}} = \frac{4b}{3c^{2}}$

$\frac{12ay^{3}}{-8a^{2}y} = \frac{12y^{3}}{-8ay} = \frac{12y^{2}}{-8a} = \frac{-3y^{2}}{2a}$

$\frac{-6p^{3}q}{-12q^{3}} = \frac{-6p^{3}}{-12q^{2}} = \frac{p^{3}}{2q^{2}}$

$\frac{-4ax^{2}}{12xy} = \frac{-4ax}{12y} = -\frac{ax}{3y}$

$\frac{9axy^{2}}{6ay^{3}} = \frac{9xy^{2}}{6y^{3}} = \frac{9x}{6y} = \frac{3x}{2y}$

$\frac{48a^{2}c^{2}}{36ac} = \frac{48ac}{36}=\frac{4ac}{3}$

$\frac{63x^{3}y^{5}}{84x^{6}y^{4}} = \frac{63x^{3}y}{84x^{6}} = \frac{63y}{84x^{3}} = \frac{3y}{4x^{3}}$
