ответ:

1. $\frac{4}{15}$ + $\frac{2}{3}$ = $\frac{4}{15}$ + $\frac{10}{15}$ = $\frac{14}{15}$

2. $\frac{3}{5}$ + $\frac{7}{10}$ = $\frac{6}{10}$ + $\frac{7}{10}$ = $\frac{13}{10}$ = 1 $\frac{3}{10}$

3. $\frac{3}{8}$ + $\frac{5}{24}$ = $\frac{9}{24}$ + $\frac{5}{24}$ = $\frac{14}{24}$ = $\frac{7}{12}$

4. $\frac{2}{3}$ + $\frac{4}{15}$ = $\frac{10}{15}$ + $\frac{4}{15}$ = $\frac{14}{15}$

5. $\frac{11}{12}$ + $\frac{5}{6}$ = $\frac{11}{12}$ + $\frac{10}{12}$ = $\frac{21}{12}$ = $\frac{7}{4}$ = 1 $\frac{3}{4}$

6. $\frac{1}{2}$ + $\frac{3}{10}$ = $\frac{5}{10}$ + $\frac{3}{10}$ = $\frac{8}{10}$ = $\frac{4}{5}$

7. $\frac{2}{5}$ + $\frac{1}{3}$ = $\frac{6}{15}$ + $\frac{5}{15}$ = $\frac{11}{15}$

8. $\frac{2}{5}$ + $\frac{1}{4}$ = $\frac{8}{20}$ + $\frac{5}{20}$ = $\frac{13}{20}$

9. $\frac{2}{3}$ + $\frac{1}{2}$ = $\frac{4}{6}$ + $\frac{3}{6}$ = $\frac{7}{6}$ = 1 $\frac{1}{6}$

10. $\frac{1}{2}$ + $\frac{2}{7}$ = $\frac{7}{14}$ + $\frac{4}{14}$ = $\frac{11}{14}$

11. $\frac{3}{4} + \frac{7}{10} = \frac{15}{20} + \frac{14}{20}$ = $\frac{29}{20} = 1\frac{9}{20}$

12. $\frac{15}{18} + \frac{11}{16} = \frac{5}{6} + \frac{11}{16} = \frac{40}{48} + \frac{33}{48} = \frac{73}{48} = 1\frac{25}{48}$

13. $\frac{7}{10} + \frac{11}{15} = \frac{21}{30} + \frac{22}{30} = \frac{43}{30} = 1\frac{13}{30}$

14. $\frac{5}{5} + \frac{7}{10} = \frac{10}{10} + \frac{7}{10} = \frac{17}{10} = 1\frac{7}{10}$

15. $\frac{4}{25} + \frac{3}{10} = \frac{8}{50} + \frac{15}{50}$ $=\frac{23}{50}$

16. $\frac{6}{7} + \frac{1}{21} = \frac{18}{21} + \frac{1}{21} = \frac{19}{21}$

17. $\frac{5}{12} + \frac{1}{15} = \frac{25}{60} + \frac{4}{60} = \frac{29}{60}$

18. $\frac{4}{15}$ + $\frac{5}{18}$ = $\frac{24}{90} + \frac{25}{90}$ = $\frac{49}{90}$

19. $\frac{5}{21} + \frac{3}{14} = \frac{10}{42} + \frac{9}{42} = \frac{19}{42}$

20. $\frac{1}{9}$ + $\frac{2}{3}$ = $\frac{1}{9} + \frac{6}{9}$ = $\frac{7}{9}$
