Ответ:

1.

$\frac{x}{ - 2.3} = \frac { - 5.8}{ - 4.6}$

$x = \frac{ - 2.3 \times ( - 5.8)}{ - 4.6}$

x=-2.9

2.

$\frac{ - 2.8}{35} = \frac{ - 4.2}{x}$

$x = \frac{35 \times ( - 4.2)}{ - 2.8}$

x=2.5

3.

$2 \frac{2}{9} = 2.2$

$11 \frac{2}{3} = 11.6$

$- 1\frac{2}{5} = - 1.4$

$x = \frac{2.2 \times ( - 1.4)}{11.6}$

x= -0.26

4.

$\frac{2}{7} = 0.28$

$\frac{3}{14} = 0.21$

$\frac{5}{6} = 0.83$

$x = \frac{0.28 \times 0.83}{0.21}$

x=1.1
