Answer 1

Ответ:

2) $\frac{10}{d^{2}p }$ 3) $-\frac{5x}{8a}$

Объяснение:

2) $\frac{12p^{2} }{7d^{4} } : \frac{6p^{3} }{35d^{2} } = \frac{12p^{2} }{7d^{4} } * \frac{35d^{2} }{6p^{3} } = \frac{2p^{2} }{d^{4} } *\frac{5d^{2} }{p^{3} } = \frac{2}{d^{2} } *\frac{5}{p} =\frac{10}{d^{2}p }$

3) $-\frac{3ab}{4xy}:(-\frac{12a^{2}b }{10x^{2} y} ) = -\frac{1}{2} * \frac{5x}{4a}=-\frac{1*5x}{2*4a} = -\frac{5x}{8a}$
