1. \(2+\frac{3}{5}=2\frac{3}{5}\).
2. \(3-\frac{10}{17}=\frac{51-10}{17}=\frac{41}{17}=2\frac{7}{17}\).
3. \(22\frac{11}{15}-22=\frac{11}{15}\).
4. \(12\frac{9}{25}+7\frac{32}{50}=19+\frac{18}{50}+\frac{32}{50}=19+1=20\).
5. \(5\frac{3}{20}-4\frac{7}{10}=1+\frac{3}{20}-\frac{14}{20}=\frac{9}{20}\).
6. \(11\frac{1}{4}+3\frac{7}{10}=14+\frac{5}{20}+\frac{14}{20}=14\frac{19}{20}\).
7. \(2+\frac{4}{7}=2\frac{4}{7}\).
8. \(5-\frac{12}{15}=5-\frac{4}{5}=4\frac{1}{5}\).
9. \(13\frac{11}{12}-10=3\frac{11}{12}\).
10. \(15\frac{7}{24}+8\frac{1}{3}=23+\frac{7}{24}+\frac{8}{24}=23\frac{15}{24}=23\frac{5}{8}\).
11. \(4\frac{4}{15}-2\frac{1}{30}=2+\frac{8}{30}-\frac{1}{30}=2\frac{7}{30}\).
12. \(12\frac{1}{5}+2\frac{5}{10}=14+\frac{2}{10}+\frac{5}{10}=14\frac{7}{10}\).
13. \(6+\frac{2}{3}=6\frac{2}{3}\).
14. \(10-\frac{15}{21}=10-\frac{5}{7}=9\frac{2}{7}\).
15. \(15\frac{1}{7}-5=10\frac{1}{7}\).
16. \(16\frac{2}{9}+2\frac{1}{18}=18+\frac{4}{18}+\frac{1}{18}=18\frac{5}{18}\).
17. \(3\frac{4}{17}-2\frac{1}{34}=1+\frac{8}{34}-\frac{1}{34}=1\frac{7}{34}\).
18. \(14\frac{2}{3}+3\frac{4}{15}=17+\frac{10}{15}+\frac{4}{15}=17\frac{14}{15}\).
