2. Найдите значение выражения: a) \(\frac{3}{14} + (\frac{2}{7} + \frac{1}{2})\) б) \(\frac{11}{56} + (\frac{6}{7} - \frac{3}{8})\) в) \((\frac{5}{8} + \frac{1}{6}) - \frac{7}{24}\) г) \(\frac{15}{36} - (\frac{1}{3} - \frac{1}{12})\)

2. Найдите значение выражения:

1. a) \(\frac{3}{14} + (\frac{2}{7} + \frac{1}{2}) = \frac{3}{14} + (\frac{4 + 7}{14}) = \frac{3}{14} + \frac{11}{14} = \frac{14}{14} = 1\)
2. б) \(\frac{11}{56} + (\frac{6}{7} - \frac{3}{8}) = \frac{11}{56} + (\frac{48 - 21}{56}) = \frac{11}{56} + \frac{27}{56} = \frac{38}{56} = \frac{19}{28}\)
3. в) \((\frac{5}{8} + \frac{1}{6}) - \frac{7}{24} = (\frac{15 + 4}{24}) - \frac{7}{24} = \frac{19}{24} - \frac{7}{24} = \frac{12}{24} = \frac{1}{2}\)
4. г) \(\frac{15}{36} - (\frac{1}{3} - \frac{1}{12}) = \frac{15}{36} - (\frac{4 - 1}{12}) = \frac{15}{36} - \frac{3}{12} = \frac{15}{36} - \frac{9}{36} = \frac{6}{36} = \frac{1}{6}\)

Ответ: a) 1; б) \(\frac{19}{28}\); в) \(\frac{1}{2}\); г) \(\frac{1}{6}\).
