(a) \(20 / 3=\frac{18+2}{3}\)
\(=18 / 3+2 / 3\)
(b) \(\frac{11}{5}=\frac{10+1}{5}=\frac{10}{5}+\frac{1}{5}=2+\frac{1}{5}=2 \frac{1}{5}\)
(c) \(\frac{17}{7}=\frac{14+3}{7}=\frac{14}{7}+\frac{3}{7}=2+\frac{3}{7}=2 \frac{3}{7}\)
(d) \(\frac{\mathbf{2 8}}{\mathbf{5}}=\frac{25+3}{5}=\frac{25}{5}+\frac{3}{5}=5+\frac{3}{5}=5 \frac{3}{5}\)
(e) \(\frac{19}{6}=\frac{18+1}{6}=\frac{18}{6}+\frac{1}{6}\)
(f) \(\frac{35}{9}=\frac{27+8}{9}=\frac{27}{9}+\frac{8}{9}=5+\frac{8}{9}=3 \frac{8}{9}\)
