Ответ:
\(3\frac{2}{7}=\frac{23}{7}\), \(\frac{5}{6}-\frac{11}{3}=\frac{5}{6}-\frac{22}{6}=-\frac{17}{6}\), \(1\frac{4}{9}=\frac{13}{9}\).
\(\frac{23}{7}:\left(-\frac{17}{6}\right)=-\frac{138}{119}\), а \(7\cdot\frac{13}{9}=\frac{91}{9}\).
\(-\frac{138}{119}+\frac{91}{9}=\frac{-1242+10829}{1071}=\frac{9587}{1071}=8\frac{1019}{1071}\).
Ответ: \(8\frac{1019}{1071}\)
