Решаем примеры на сложение дробей:
1) \(\frac{2}{5} + \frac{1}{10} = \frac{4}{10} + \frac{1}{10} = \frac{5}{10} = \frac{1}{2}\)
2) \(\frac{5}{6} + \frac{2}{3} = \frac{5}{6} + \frac{4}{6} = \frac{9}{6} = \frac{3}{2} = 1\frac{1}{2}\)
3) \(\frac{3}{4} + \frac{7}{12} = \frac{9}{12} + \frac{7}{12} = \frac{16}{12} = \frac{4}{3} = 1\frac{1}{3}\)
4) \(\frac{2}{15} + \frac{4}{5} = \frac{2}{15} + \frac{12}{15} = \frac{14}{15}\)
5) \(\frac{5}{7} + \frac{3}{14} = \frac{10}{14} + \frac{3}{14} = \frac{13}{14}\)
6) \(\frac{3}{11} + \frac{6}{55} = \frac{15}{55} + \frac{6}{55} = \frac{21}{55}\)
7) \(\frac{1}{6} + \frac{1}{9} = \frac{3}{18} + \frac{2}{18} = \frac{5}{18}\)
8) \(\frac{1}{10} + \frac{1}{15} = \frac{3}{30} + \frac{2}{30} = \frac{5}{30} = \frac{1}{6}\)
9) \(\frac{2}{8} + \frac{1}{12} = \frac{6}{24} + \frac{2}{24} = \frac{8}{24} = \frac{1}{3}\)
10) \(\frac{1}{9} + \frac{1}{2} = \frac{2}{18} + \frac{9}{18} = \frac{11}{18}\)
