a) \(\frac{67}{95} + \frac{24}{95} = \frac{67+24}{95} = \frac{91}{95}\)

Ответ: \(\frac{91}{95}\)

б) \(\frac{87}{95} - \frac{64}{95} = \frac{87-64}{95} = \frac{23}{95}\)

Ответ: \(\frac{23}{95}\)

в) \(\frac{15}{71} + \frac{11}{71} + \frac{35}{71} = \frac{15+11+35}{71} = \frac{61}{71}\)

Ответ: \(\frac{61}{71}\)

г) \(\frac{11}{29} + \frac{13}{29} - \frac{23}{29} = \frac{11+13-23}{29} = \frac{1}{29}\)

Ответ: \(\frac{1}{29}\)

д) \(\frac{74}{89} - \frac{70}{89} + \frac{35}{89} = \frac{74-70+35}{89} = \frac{39}{89}\)
