222. Выполните действие и сократите результат: 1) \(\frac{16}{63} + \frac{12}{63}\); 2) \(\frac{53}{85} - \frac{19}{85}\); 3) \(8\frac{34}{81} + 2\frac{38}{81}\); 4) \(3\frac{49}{56} - 1\frac{3}{56}\)

1) \(\frac{16}{63} + \frac{12}{63} = \frac{28}{63} = \frac{4}{9}\) 2) \(\frac{53}{85} - \frac{19}{85} = \frac{34}{85}\) 3) \(8\frac{34}{81} + 2\frac{38}{81} = 10\frac{72}{81} = 10\frac{8}{9}\) 4) \(3\frac{49}{56} - 1\frac{3}{56} = 2\frac{46}{56} = 2\frac{23}{28}\)
