Выполните деление:
а) $\frac{6x^2}{m^3n} : \frac{x}{3mn^2}$;
б) $\frac{35x^2y}{12ab} : \frac{7xy}{8ab^2}$;
в) $\frac{8mx^2}{3y^3} : (4m^2x)$;
г) $15a^2bx : \frac{a^3b^2}{30x^2}$.
$\frac{6x^2}{m^3n} : \frac{x}{3mn^2} = \frac{6x^2}{m^3n} * \frac{3mn^2}{x} = \frac{6x}{m^2} * \frac{3n}{1} = \frac{18nx}{m^2}$
$\frac{35x^2y}{12ab} : \frac{7xy}{8ab^2} = \frac{35x^2y}{12ab} * \frac{8ab^2}{7xy} = \frac{5x}{3} * \frac{2b}{1} = \frac{10bx}{3}$
$\frac{8mx^2}{3y^3} : (4m^2x) = \frac{8mx^2}{3y^3} * \frac{1}{4m^2x} = \frac{2x}{3y^3} * \frac{1}{m} = \frac{2x}{3my^3}$
$15a^2bx : \frac{a^3b^2}{30x^2} = 15a^2bx * \frac{30x^2}{a^3b^2} = 15x * \frac{30x^2}{ab} = \frac{450x^3}{ab}$
