Answer 1

Ответ:

1)

$( - 7 \frac{1}{2}) \div ( - 5) = \frac{15}{2} \times \frac{1}{5} = \frac{3}{2} = 1.5$

2)

$- \frac{8}{11} \div ( - 4) = \frac{8}{11} \times \frac{1}{4} = \frac{2}{11}$

3)

$- 4 \frac{5}{7} \div \frac{11}{4} = - \frac{33}{7} \times \frac{4}{11} = - \frac{3}{7} \times 4 = - \frac{12}{7} = 1 \frac{5}{7}$

4)

$- 11.7 \div ( - 1.8) = 11.7 \div 1.8 = 6.5$

5)

$10.64 \div ( - 1.4) = - (10.64 \div 1.4) = - 7.6$

6)

$- 8.6 \times ( - 2.5) = 8.6 \times 2.5 = 21.5$

7)

$- 4.04 \times 1.5 = - 6.06$

8)

$3.57 \div ( - 0.7) = - 5.1$

9)

$- 8.32 \div ( - 6.4) = 1.3$
