Answer 1

1) $-2\frac{2}{3} * \frac{3}{8} * (-3\frac{1}{3} )$

$-2\frac{2}{3} * \frac{3}{8} = -\frac{8}{3} * \frac{3}{8} = -\frac{8*3}{3*8} = -1$

$-1 * (-3\frac{1}{3} ) = 3\frac{1}{3}$

Ответ: $3\frac{1}{3}$.

2) $2\frac{2}{5} *(-\frac{5}{6}) *(-\frac{7}{10})$

$2\frac{2}{5} *(-\frac{5}{6}) = \frac{12}{5} * (-\frac{5}{6}) =- \frac{12*5}{5*6} = -2$

$-2 * (-\frac{7}{10}) = 2 * \frac{7}{10} = \frac{2*7}{10} = \frac{14}{10} = 1\frac{4}{10} = 1\frac{2}{5} = 1,4$

Ответ: 1,4.
