пожалуйста помогите ​

Answer 1

Ответ:

$\frac{2x}{a} \times \frac{a}{8x} = \frac{1}{4}$

$- \frac{ 3b}{2c} \times \frac{c}{9b} = - \frac{1}{3c}$

$\frac{ {m}^{2}n}{15p} \times \frac{5p}{m {n}^{2} } = \frac{m}{3n}$

$\frac{35 {x}^{4} }{18 {y}^{2} } \times \frac{9y}{14 {x}^{2} } = \frac{5 {x}^{2} }{6y}$

$8b \times \frac{y}{4 {b}^{2} } = \frac{2y}{b}$

$\frac{3 {a}^{2} }{ {b}^{2} } \times {b}^{3} =3 {a}^{2}b$
