\(\dfrac{4}{-33}-\dfrac{5}{11}+\dfrac{-4}{-33}+\dfrac{-8}{3}\)
\(=\dfrac{4}{-33}-\dfrac{5}{11}+\dfrac{4}{33}+-\dfrac{8}{3}\)
\(=\left(\dfrac{4}{-33}+\dfrac{4}{33}\right)+\left(-\dfrac{5}{11}+\dfrac{-8}{3}\right)\)
\(=0+\left(\dfrac{-15}{33}+\dfrac{-88}{33}\right)\)
\(=0+\dfrac{-103}{33}=\dfrac{-103}{33}\)

a: \(\Leftrightarrow x=\dfrac{33}{20}:\dfrac{11}{8}=\dfrac{33}{20}\cdot\dfrac{8}{11}=3\cdot\dfrac{2}{5}=\dfrac{6}{5}\)
b: \(\Leftrightarrow x=5:\dfrac{4}{7}=\dfrac{35}{4}\)

\(\dfrac{8}{11}-\dfrac{8}{44}\times\dfrac{3}{4}=\dfrac{8}{11}-\dfrac{8\times3}{33\times4}=\dfrac{8}{11}-\dfrac{2}{11}=\dfrac{6}{11}\)

\(\dfrac{11}{8}\cdot\left[\left(-\dfrac{5}{11}:\dfrac{13}{8}-\dfrac{5}{11}:\dfrac{13}{15}\right)+\dfrac{-6}{33}\right]+\dfrac{-3}{4}\)
\(=\dfrac{11}{8}\cdot\left[\left(-\dfrac{5}{11}\cdot\dfrac{8}{13}-\dfrac{5}{11}\cdot\dfrac{15}{13}\right)-\dfrac{2}{11}\right]-\dfrac{3}{4}\)
\(=\dfrac{11}{8}\cdot\left[-\dfrac{5}{11}\cdot\left(\dfrac{8}{13}+\dfrac{15}{13}\right)-\dfrac{2}{11}\right]-\dfrac{3}{4}\)
\(=\dfrac{11}{8}\cdot\left(-\dfrac{5}{11}\cdot\dfrac{23}{13}-\dfrac{2}{11}\right)-\dfrac{3}{4}\)
\(=\dfrac{11}{8}\cdot\left(-\dfrac{115}{143}-\dfrac{2}{11}\right)-\dfrac{3}{4}\)
\(=\dfrac{11}{8}\cdot\dfrac{-141}{143}-\dfrac{3}{4}\)
\(=-\dfrac{141}{104}-\dfrac{3}{4}\)
\(=-\dfrac{219}{104}\)
8 /11 + 8 /33 × 3 /4 = 8 /11 + 2 /11 = 10 /11
