Answer 1

Ответ:

1) 22/3 - 1/5 - 16/15 = 6 целых 1/15

22/3 - 1/5 = (НОЗ: 15) = 22*5/15 - 1*3/15 = 110/15 - 3/15 = 107/15 = 7 целых 2/15

107/15 - 16/15 = 91/15 = 6 целых 1/15

2) 31/8 - 5/4 - 1/2 = 2 целых 1/8

31/8 - 5/4 = (НОЗ: 8) = 31*1/8 - 5*2/8 = 31/8 - 10/8 = 21/8 = 2 целых 5/8

21/8 - 1/2 = (НОЗ: 8) = 21*1/8 - 1*4/8 = 21/8 - 4/8 = 17/8 = 2 целых 1/8

3) 43/9 - 5/3 + 1/6 = 3 целых 5/18

43/9 - 5/3 = (НОЗ: 9) = 43*1/9 - 5*3/9 = 43/9 - 15/9 = 28/9 = 3 целых 1/9

28/9 + 1/6 = (НОЗ: 18) = 28*2/18 + 1*3/18 = 56/18 + 3/18 = 59/18 = 3 целых 5/18
