Сократите дроби:
а) $\frac{x - y}{y - x}$;
б) $\frac{2(a - b)}{3(b - a)}$;
в) $\frac{4mn(m - n)}{2m(n - m)}$;
г) $\frac{6a^2b^3(3 - a)}{14ab^3(a - 3)}$.
$\frac{x - y}{y - x} = -\frac{y - x}{y - x} = -1$
$\frac{2(a - b)}{3(b - a)} = -\frac{2(a - b)}{3(a - b)} = -\frac{2}{3}$
$\frac{4mn(m - n)}{2m(n - m)} = -\frac{4mn(m - n)}{2m(m - n)} = -\frac{4mn}{2m} = -2n$
$\frac{6a^2b^3(3 - a)}{14ab^3(a - 3)} = -\frac{6a^2b^3(a - 3)}{14ab^3(a - 3)} = -\frac{6a^2b^3}{14ab^3} = -\frac{3a}{7}$
