5.359 Выполните действие и сократите дробную часть полученного результата: a) \( \frac{14}{18} - \frac{5}{18} \) b) \( \frac{5}{22} + \frac{6}{22} \) c) \( 6 \frac{7}{12} - 1 \frac{3}{12} \) г) \( 7 \frac{5}{27} + 3 \frac{1}{27} \)

a) \( \frac{14}{18} - \frac{5}{18} = \frac{14-5}{18} = \frac{9}{18} = \frac{1}{2} \) b) \( \frac{5}{22} + \frac{6}{22} = \frac{5+6}{22} = \frac{11}{22} = \frac{1}{2} \) c) \( 6 \frac{7}{12} - 1 \frac{3}{12} = (6 - 1) + (\frac{7}{12} - \frac{3}{12}) = 5 + \frac{4}{12} = 5 + \frac{1}{3} = 5 \frac{1}{3} \) г) \( 7 \frac{5}{27} + 3 \frac{1}{27} = (7 + 3) + (\frac{5}{27} + \frac{1}{27}) = 10 + \frac{6}{27} = 10 + \frac{2}{9} = 10 \frac{2}{9} \)
