\(-\frac{12}{5}:\frac{7}{11}-\frac{23}{5}:\frac{7}{11}-\frac{5}{11}\)
\(=-\frac{12}{5}.\frac{11}{7}-\frac{23}{5}.\frac{11}{7}-\frac{5}{11}\)
\(=\left(-\frac{12}{5}-\frac{23}{5}\right).\frac{11}{7}+\frac{5}{11}\)
\(=-7.\frac{11}{7}-\frac{5}{11}\)
\(=-\frac{16}{11}\)
\(\frac{-12}{35}:\frac{7}{11}-\frac{23}{5}:\frac{7}{11}-\frac{5}{11}\)
\(=\frac{-12}{35}.\frac{11}{7}-\frac{23}{5}.\frac{11}{7}-\frac{5}{11}\)
\(=\frac{-132}{245}-\frac{253}{35}-\frac{5}{11}\)
\(=\frac{-132}{245}-\frac{1771}{245}-\frac{5}{11}\)
\(=\frac{-1903}{245}-\frac{5}{11}\)
\(=\frac{-22158}{2695}\)
