помогите срочно пажалуйста

Answer 1

Ответ:

$- 3 \frac{1}{3} \times 1 \frac{1}{2} = \frac{ - 10}{3} \times \frac{3}{2} = \frac{ - 10 \times 3}{3 \times 2} = - 5$

$- 1.8 \times ( - 50) = - 1 \frac{4}{5} \times ( - 50) = - \frac{9}{5} \times ( - 50) = - \frac{9 \times ( - 50)}{5} = \frac{450}{5} = 90$

$288 \div ( - 2.4) = 288 \div ( - 2 \frac{2}{5} ) = 288 \div ( - \frac{12}{5} ) = \frac{288 \times 5}{5} = \frac{1440}{5} = 288$
