\[\frac{2}{11} < x < \frac{4}{11}\]
\[\frac{2}{11} \cdot \frac{3}{3} = \frac{6}{33};\ \ \ \ \ \ \ \ \frac{4}{11} \cdot \frac{3}{3} = \frac{12}{33}\]
\[\frac{6}{33} < x < \frac{12}{33}\]
\[x = \left\{ \frac{7}{33};\ \ \frac{8}{33};\ \ \frac{9}{33};\ \ \frac{10}{33} \right\}.\]
\[Ответ:\ \frac{7}{33};\ \ \frac{8}{33};\ \ \frac{9}{33};\ \ \frac{10}{33}.\]
