Примеры решены следующим образом: 1. \( \frac{5}{8} + \frac{10}{5} = \frac{5}{8} + 2 = \frac{21}{8} \). 2. \( \frac{7}{6} + \frac{9}{30} = \frac{35}{30} + \frac{9}{30} = \frac{44}{30} = \frac{22}{15} \). 3. \( \frac{8}{2} + \frac{4}{24} = 4 + \frac{1}{6} = \frac{25}{6} \). 4. \( \frac{5}{8} - \frac{4}{64} = \frac{5}{8} - \frac{1}{16} = \frac{10}{16} - \frac{1}{16} = \frac{9}{16} \). 5. \( \frac{6}{12} + \frac{12}{4} = \frac{1}{2} + 3 = \frac{7}{2} \). 6. \( \frac{2}{8} - \frac{2}{72} = \frac{1}{4} - \frac{1}{36} = \frac{9}{36} - \frac{1}{36} = \frac{8}{36} = \frac{2}{9} \). 7. \( \frac{9}{16} + \frac{4}{24} - \frac{3}{8} = \frac{27}{48} + \frac{8}{48} - \frac{18}{48} = \frac{17}{48} \). 8. \( \frac{1}{3} - \frac{1}{6} + \frac{1}{4} = \frac{2}{6} - \frac{1}{6} + \frac{3}{12} = \frac{1}{6} + \frac{1}{4} = \frac{2}{12} + \frac{3}{12} = \frac{5}{12} \). 9. \( \frac{1}{6} + \frac{1}{4} - \frac{1}{7} = \frac{14}{84} + \frac{21}{84} - \frac{12}{84} = \frac{23}{84} \). 10. \( \frac{9}{14} - \frac{3}{7} + \frac{15}{28} = \frac{18}{28} - \frac{12}{28} + \frac{15}{28} = \frac{21}{28} = \frac{3}{4} \).
