Решение:
а) \(\frac{4}{11} + \frac{1}{11} = \frac{4+1}{11} = \frac{5}{11}\)
Ответ: \(\frac{5}{11}\)
б) \(\frac{7}{10} - \frac{1}{10} = \frac{7-1}{10} = \frac{6}{10} = \frac{3}{5}\)
Ответ: \(\frac{3}{5}\)
в) \(\frac{3}{14} + \frac{1}{14} = \frac{3+1}{14} = \frac{4}{14} = \frac{2}{7}\)
Ответ: \(\frac{2}{7}\)
г) \(\frac{12}{17} - \frac{4}{17} = \frac{12-4}{17} = \frac{8}{17}\)
Ответ: \(\frac{8}{17}\)
