\[\frac{3}{8} < x < \frac{5}{8}\]
\[\frac{3}{8} \cdot \frac{3}{3} = \frac{9}{24};\ \ \ \ \ \ \frac{5}{8} \cdot \frac{3}{3} = \frac{15}{24}\]
\[\frac{9}{24} < x < \frac{15}{24}\]
\[x = \left\{ \frac{10}{24};\ \ \frac{11}{24};\ \ \frac{12}{24};\ \frac{13}{24} \right\}.\]
\[Ответ:\ \frac{10}{24};\ \ \frac{11}{24};\ \ \frac{12}{24};\ \frac{13}{24}.\]
