\(a.\frac{7}{3}+\frac{5}{6}+\frac{1}{9}\)
\(=\frac{42}{18}+\frac{15}{18}+\frac{2}{18}\)
\(=\frac{42+15+2}{18}\)
\(=\frac{59}{18}\)

\(b.11+\frac{3}{14}-\frac{4}{7}\)
\(=\frac{154}{14}+\frac{3}{14}-\frac{4}{7}\)
\(=\frac{154}{14}+\frac{3}{14}-\frac{8}{14}\)
\(=\frac{154+3-8}{14}\)
\(=\frac{149}{14}\)
