Answer 1

1)

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

2)

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

3)

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

4)

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

5)

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

6)

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

7)

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

8)

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