Answer 1

Ответ:

$\frac{ - 30}{ - 5} = 6 \: \: \: \: \frac{25}{ - 5} = - 5 \: \: \: \: \frac{ - 12}{ - 5} = 2.4 \: \: \: \: \frac{ - 0.5}{ - 5} = 0.1 \: \: \: \: \frac{ \frac{1}{10} }{ - 5} = \frac{1}{ - 50}$

$25 \times 4 = 100 \\ - 2.5 \times 4 = - 10 \\ - 0.25 \times 4 = - 1 \\ \frac{ - 7 \times 9}{90} = \frac{ - 7}{10} = - 0.7 \\ \frac{ - 7 \times ( - 9)}{900} = \frac{7}{100} = 0.07 \\ \frac{7 \times ( - 9)}{9000} = \frac{7}{1000} = 0.007 \\ \frac{9 \times ( - 8)}{4} = - 18 \\ \frac{ - 9 \times ( - 80)}{4} = 180 \\ \frac{9 \times ( - 800)}{4} = - 1800$
