1. Выполните вычисление: A) \(\frac{4}{10} + \frac{5}{10}\) Б) \(\frac{11}{7} - \frac{7}{7}\) В) \(1 - \frac{7}{11}\)

Решение:

1. A) \(\frac{4}{10} + \frac{5}{10} = \frac{4+5}{10} = \frac{9}{10}\)
2. Б) \(\frac{11}{7} - \frac{7}{7} = \frac{11-7}{7} = \frac{4}{7}\)
3. В) \(1 - \frac{7}{11} = \frac{11}{11} - \frac{7}{11} = \frac{11-7}{11} = \frac{4}{11}\)

Ответ: A) \(\frac{9}{10}\), Б) \(\frac{4}{7}\), В) \(\frac{4}{11}\).
