a) 4 13/24 + 1/8 - 3 1/24 = 4 13/24 + 3/24 - 3 1/24 = 4 16/24 - 3 1/24 = 1 15/24 = 1 5/8
Ответ: 1 5/8
б) 3 8/9 + 1 1/4 + 1/9 = 3 9/9 + 1 1/4 = 4 + 1 1/4 = 5 1/4
Ответ: 5 1/4
в) 5 1/2 - 2 7/12 - 2 3/10 = 5 6/12 - 2 7/12 - 2 3/10 = 4 18/12 - 2 7/12 - 2 3/10 = 2 11/12 - 2 3/10 = 2 55/60 - 2 18/60 = 37/60
Ответ: 37/60
г) 4 2/4 + 2 3/4 - 1 5/12 = 4 6/12 + 2 9/12 - 1 5/12 = 6 15/12 - 1 5/12 = 5 10/12 = 5 5/6
Ответ: 5 5/6
