22. Найдите сумму: 1) 8 3/8 + 3 5/8; 2) 5 8/11 + 3 10/11; 3) 9 13/24 + 12/24

1. \(8\dfrac{3}{8}+3\dfrac{5}{8}=11\dfrac{8}{8}=12\).
2. \(5\dfrac{8}{11}+3\dfrac{10}{11}=8\dfrac{18}{11}=9\dfrac{7}{11}\).
3. \(9\dfrac{13}{24}+\dfrac{12}{24}=9\dfrac{25}{24}=10\dfrac{1}{24}\).

Ответ: 1) 12; 2) \(9\dfrac{7}{11}\); 3) \(10\dfrac{1}{24}\).
