  1. \(2\frac{5}{8}=\frac{2\cdot8+5}{8}=\frac{21}{8}\).
  2. \(1\frac{1}{10}=\frac{1\cdot10+1}{10}=\frac{11}{10}\).
  3. \(1\frac{4}{10}=\frac{1\cdot10+4}{10}=\frac{14}{10}=\frac{7}{5}\).
  4. \(10\frac{2}{6}=\frac{10\cdot6+2}{6}=\frac{62}{6}=\frac{31}{3}\).
  5. \(35\frac{5}{4}=\frac{35\cdot4+5}{4}=\frac{145}{4}\).
  6. \(20\frac{3}{8}=\frac{20\cdot8+3}{8}=\frac{163}{8}\).
  7. \(11\frac{5}{8}=\frac{11\cdot8+5}{8}=\frac{93}{8}\).
  8. \(61\frac{2}{4}=\frac{61\cdot4+2}{4}=\frac{246}{4}=\frac{123}{2}\).
  9. \(5\frac{6}{9}=\frac{5\cdot9+6}{9}=\frac{51}{9}=\frac{17}{3}\).
