Прошу помогите.........

Answer 1

Объяснение:

а)

$\frac{32}{15} \times \frac{75}{16} = \frac{32}{15} \times 5 = \frac{32}{3} = 10 \frac{2}{3}$

б)

$\frac{2x}{3} \div x = \frac{3x}{3} \times \frac{1}{x} = \frac{2}{3}$

в)

$\frac{x {}^{2} }{4} \div ( - \frac{1}{2x} ) = - \frac{x {}^{2} }{4} \times 2x = - \frac{x {}^{2} }{2} \times x = - \frac{x {}^{3} }{2}$
