Answer 1

$1)\frac{x^{2}-xy }{x^{2}y-xy^{2} }=\frac{x(x-y)}{xy(x-y)}=\boxed{\frac{1}{y}}\\\\\\2)\frac{pq^{4}-cq^{4}}{cq^{3}-pq^{3}}=\frac{q^{4}(p-c) }{q^{3}(c-p) }=\boxed{-q} \\\\\\3)\frac{ma^{2}-m^{2}a}{m^{2}-ma }=\frac{ma(a-m)}{m(m-a)}=\boxed{-a}\\\\4)\frac{2nd^{4}-4pd^{4}}{3nd^{3}-6pd^{3}} =\frac{2d^{4}(n-2p) }{3d^{3}(n-2p)}=\boxed{\frac{2d}{3} }$
