Можешь выполнить сложение или вычитание?

Конечно, давай помогу! Тут нужно сложить или вычесть дроби. Сейчас всё решим по порядку. 1. $\frac{1}{2} + \frac{3}{8} = \frac{4}{8} + \frac{3}{8} = \frac{7}{8}$ 2. $\frac{2}{7} + \frac{5}{14} = \frac{4}{14} + \frac{5}{14} = \frac{9}{14}$ 3. $\frac{3}{5} + \frac{4}{15} = \frac{9}{15} + \frac{4}{15} = \frac{13}{15}$ 4. $\frac{1}{8} + \frac{3}{16} = \frac{2}{16} + \frac{3}{16} = \frac{5}{16}$ 5. $\frac{2}{9} + \frac{5}{18} = \frac{4}{18} + \frac{5}{18} = \frac{9}{18} = \frac{1}{2}$ 6. $\frac{8}{13} - \frac{1}{26} = \frac{16}{26} - \frac{1}{26} = \frac{15}{26}$ 7. $\frac{7}{15} - \frac{7}{30} = \frac{14}{30} - \frac{7}{30} = \frac{7}{30}$ 8. $\frac{2}{19} - \frac{1}{38} = \frac{4}{38} - \frac{1}{38} = \frac{3}{38}$ 9. $\frac{5}{7} - \frac{3}{14} = \frac{10}{14} - \frac{3}{14} = \frac{7}{14} = \frac{1}{2}$ 10. $\frac{4}{21} - \frac{1}{7} = \frac{4}{21} - \frac{3}{21} = \frac{1}{21}$ 11. $\frac{7}{20} + \frac{11}{50} = \frac{35}{100} + \frac{22}{100} = \frac{57}{100}$ 12. $\frac{17}{33} - \frac{5}{22} = \frac{34}{66} - \frac{15}{66} = \frac{19}{66}$ 13. $\frac{27}{76} - 0 = \frac{27}{76}$ 14. $\frac{9}{20} + \frac{5}{8} = \frac{18}{40} + \frac{25}{40} = \frac{43}{40} = 1 \frac{3}{40}$ 15. $\frac{2}{7} + \frac{13}{28} = \frac{8}{28} + \frac{13}{28} = \frac{21}{28} = \frac{3}{4}$ 16. $\frac{5}{13} - \frac{14}{39} = \frac{15}{39} - \frac{14}{39} = \frac{1}{39}$ 17. $\frac{5}{8} - \frac{2}{7} = \frac{35}{56} - \frac{16}{56} = \frac{19}{56}$ 18. $\frac{3}{4} + \frac{5}{12} = \frac{9}{12} + \frac{5}{12} = \frac{14}{12} = 1 \frac{2}{12} = 1 \frac{1}{6}$ 19. $\frac{15}{23} - \frac{27}{46} = \frac{30}{46} - \frac{27}{46} = \frac{3}{46}$ 20. $\frac{9}{25} + \frac{14}{117} = \frac{1053}{2925} + \frac{350}{2925} = \frac{1403}{2925}$ 21. $\frac{17}{35} + \frac{13}{28} = \frac{476}{980} + \frac{455}{980} = \frac{931}{980}$ 22. $1 - \frac{2}{7} = \frac{7}{7} - \frac{2}{7} = \frac{5}{7}$ 23. $1 \frac{17}{33} + \frac{5}{22} = 1 \frac{34}{66} + \frac{15}{66} = 1 \frac{49}{66}$ 24. $5 \frac{1}{12} - \frac{7}{10} = 5 \frac{5}{60} - \frac{42}{60} = 4 \frac{65}{60} - \frac{42}{60} = 4 \frac{23}{60}$ 25. $12 \frac{3}{10} - 5 \frac{11}{15} = 12 \frac{9}{30} - 5 \frac{22}{30} = 11 \frac{39}{30} - 5 \frac{22}{30} = 6 \frac{17}{30}$ 26. $7 \frac{7}{15} - \frac{3}{20} = 7 \frac{28}{60} - \frac{9}{60} = 7 \frac{19}{60}$ 27. $5 \frac{1}{9} + 3 \frac{2}{5} = 5 \frac{5}{45} + 3 \frac{18}{45} = 8 \frac{23}{45}$ 28. $3 \frac{3}{8} + 1 \frac{5}{12} = 3 \frac{9}{24} + 1 \frac{10}{24} = 4 \frac{19}{24}$ 29. $62 \frac{2}{3} - 3 \frac{5}{8} = 62 \frac{16}{24} - 3 \frac{15}{24} = 59 \frac{1}{24}$ 30. $12 - 10 \frac{7}{9} = 11 \frac{9}{9} - 10 \frac{7}{9} = 1 \frac{2}{9}$ 31. $7 \frac{7}{8} - 1 \frac{9}{10} = 7 \frac{35}{40} - 1 \frac{36}{40} = 6 \frac{75}{40} - 1 \frac{36}{40} = 5 \frac{39}{40}$ 32. $18 - 11 \frac{8}{13} = 17 \frac{13}{13} - 11 \frac{8}{13} = 6 \frac{5}{13}$ 33. $15 \frac{3}{17} - \frac{4}{17} = 15 \frac{3}{17} - \frac{4}{17} = 14 \frac{17+3}{17} - \frac{4}{17} = 14 \frac{20}{17} - \frac{4}{17} = 14 \frac{16}{17}$ Надеюсь, теперь тебе стало понятнее, как решать такие примеры! Если что, обращайся!
