\(2\frac{1}{11}=\frac{23}{11}\).
\(\frac{23}{11}\cdot\frac{11}{12}:\frac{7}{18}=\frac{23}{12}\cdot\frac{18}{7}=\frac{69}{14}\).
\(14-\frac{69}{14}=\frac{196-69}{14}=\frac{127}{14}\).
\(4\frac{7}{8}=\frac{39}{8}\), поэтому \(\frac{127}{14}:\frac{39}{8}=\frac{127}{14}\cdot\frac{8}{39}=\frac{508}{273}\).
Ответ: \(\frac{508}{273}=1\frac{235}{273}\).
