Сократите дроби:
а) $\frac{2(x + y)}{4ax}$;
б) $\frac{a + b}{a + b}$;
в) $\frac{2(x - 1)}{5(x - 1)}$;
г) $\frac{3a(a - b)^2}{6a(a - b)^2}$;
д) $\frac{4x(x - y)^3}{16x^2y(x - y)}$;
е) $\frac{25m^2n(a - b)}{35mn^2(a - b)^2}$;
ж) $\frac{2p(p - q)(p^2 + q^2)}{4q(p - q)(p^2 + q^2)}$;
з) $\frac{8a(a + b)^2(a - b)}{18a(a - b)(a + b)}$.
$\frac{2(x + y)}{4ax} = \frac{x + y}{2ax}$
$\frac{a + b}{a + b} = 1$
$\frac{2(x - 1)}{5(x - 1)} = \frac{2}{5}$
$\frac{3a(a - b)^2}{6a(a - b)^2} = \frac{3a}{6a} = \frac{1}{2}$
$\frac{4x(x - y)^3}{16x^2y(x - y)} = \frac{4x(x - y)^2}{16x^2y} = \frac{(x - y)^2}{4xy}$
$\frac{25m^2n(a - b)}{35mn^2(a - b)^2} = \frac{25m^2n}{35mn^2(a - b)} = \frac{5m}{7n(a - b)}$
$\frac{2p(p - q)(p^2 + q^2)}{4q(p - q)(p^2 + q^2)} = \frac{2p}{4q} = \frac{p}{2q}$
$\frac{8a(a + b)^2(a - b)}{18a(a - b)(a + b)} = \frac{8a(a + b)}{18a} = \frac{4(a + b)}{9}$
