Answer 1

Ответ:

$18 \frac{2}{3}$

Пошаговое объяснение:

$- 3 \frac{5}{9} \times ( - 5 \frac{1}{4} ) = - \frac{32}{9} \times ( - \frac{21}{4} ) = \frac{32}{9} \times \frac{21}{4} = \frac{8}{3} \times 7 = \frac{8}{3} \times \frac{7}{1} = \frac{8 \times 7}{3 \times 1} = \frac{56}{3} = 18 \frac{2}{3}$
