\(\frac{3}{11}\times\frac{7}{19}+\frac{3}{11}\times\frac{8}{19}-\frac{4}{9}:\frac{11}{3}\)

\(=\frac{3}{11}\times\frac{7}{9}+\frac{3}{11}\times\frac{8}{9}-\frac{4}{9}\times\frac{3}{11}\)

\(=\frac{3}{11}\times\left(\frac{7}{9}+\frac{8}{9}-\frac{4}{9}\right)\)

\(=\frac{3}{11}\times\frac{11}{9}\)

\(=\frac{1}{2}\)
