Решите пожалуйста поставлю 10 балов

Answer 1

1) 1 7/9 + 3 4/9 = (1+3) + (7/9 + 4/9) = 4 + (7/9 + 4/9) = 4 + 11/9 = 4 + 1 2/9 = 4 + 1 +         2/9 = 5 + 2/9 = 5 2/9

2) 4 5/13 + 2 9/12 = (4+2) + (5/13 + 9/12) = 6 + (5/13 + 9/12) = 6 + 59/52 = 6 +

+ 1 7/52 = 6 + 1 + 7/52 = 7 + 7/52 = 7 7/52

Ответ: 5 2/9; 7 7/52
