Решите уравнение:х:3=1/7:1 1/14

$\frac{x}{3} = \frac{ \frac{1}{7} }{1 \frac{1}{14} }$
$\frac{x}{3} = \frac{ \frac{1}{7} }{ \frac{15}{14} }$

$\frac{15}{14} x = \frac{1}{7} \times 3$

$\frac{15}{14} x = \frac{1 \times 3}{7}$

$\frac{15}{14} x = \frac{3}{7}$

$x = \frac{3}{7} \div \frac{15}{14} = \frac{3}{7} \times \frac{14}{15}$

$x = \frac{3 \times 14}{7 \times 15} = \frac{1 \times 2}{1 \times 5}$

$x = \frac{2}{5}$

Ответ: х=2/5
