\[1)\ \frac{2}{11} < x < \frac{3}{11}\]

\[\frac{12}{66} < x < \frac{18}{66}\]

\[x = \frac{13}{66};\ \frac{15}{66} = \frac{5}{22};\ \frac{17}{66}.\]

\[2)\ \frac{1}{8} < x < \frac{1}{7}\]

\[\frac{7}{56} < x < \frac{8}{56}\]

\[\frac{28}{224} < x < \frac{32}{224}\]

\[x = \frac{29}{244};\frac{30}{224} = \frac{15}{112};\ \frac{31}{224}.\]
