Question

1) 3,5:* = 2:0,4
2) *:4,4 = 6:12
с решением​

Answer 1

Ответ:

1)$\frac{3.5}{x} = \frac{2}{0.4}$

$\frac{3.5}{x} = 5$

$x = 3.5 \div 5$

$x = 0.7$

2)$\frac{x}{4.4} = \frac{6}{12}$

$12 \times x = 6 \times 4.4$

$12x = 26.4$

$x = 26.4 \div 12$

$x = 2.2$

Answer 2

Ответ:

$\frac{3.5}{x}$$=\frac{2}{0.4}=$$\frac{3.5*0.4}{2}$$=0.7$

$\frac{x}{4.4}=\frac{6}{12}=\frac{4.4*6}{12}=2.2$
