2. \(1\frac{19}{25}=\frac{1\cdot25+19}{25}=\frac{44}{25}\)
3. \(3\frac{4}{9}=\frac{3\cdot9+4}{9}=\frac{31}{9}\)
4. \(5\frac{1}{3}=\frac{5\cdot3+1}{3}=\frac{16}{3}\)
5. \(6\frac{2}{5}=\frac{6\cdot5+2}{5}=\frac{32}{5}\)
6. \(2\frac{6}{13}=\frac{2\cdot13+6}{13}=\frac{32}{13}\)
7. \(7\frac{1}{5}=\frac{7\cdot5+1}{5}=\frac{36}{5}\)
8. \(5\frac{5}{11}=\frac{5\cdot11+5}{11}=\frac{60}{11}\)
9. \(6\frac{2}{7}=\frac{6\cdot7+2}{7}=\frac{44}{7}\)
10. \(3\frac{1}{9}=\frac{3\cdot9+1}{9}=\frac{28}{9}\)
11. \(29\frac{1}{2}=\frac{29\cdot2+1}{2}=\frac{59}{2}\)
12. \(7\frac{5}{8}=\frac{7\cdot8+5}{8}=\frac{61}{8}\)
13. \(9\frac{3}{4}=\frac{9\cdot4+3}{4}=\frac{39}{4}\)
14. \(11\frac{3}{5}=\frac{11\cdot5+3}{5}=\frac{58}{5}\)
15. \(13\frac{1}{2}=\frac{13\cdot2+1}{2}=\frac{27}{2}\)
16. \(7\frac{4}{5}=\frac{7\cdot5+4}{5}=\frac{39}{5}\)
17. \(3\frac{5}{6}=\frac{3\cdot6+5}{6}=\frac{23}{6}\)
18. \(13\frac{4}{9}=\frac{13\cdot9+4}{9}=\frac{121}{9}\)
19. \(5\frac{1}{8}=\frac{5\cdot8+1}{8}=\frac{41}{8}\)
20. \(4\frac{5}{7}=\frac{4\cdot7+5}{7}=\frac{33}{7}\)
