Ответ:

1 1/9 + 2,75 + 1/3 = 1 1/9 + 2 75/100 + 1/3 = 1 100/900 + 2 675/900 + 300/900 = 3 1075/900 = 4 175/900 = 4 7/36

8,5 + 5/6 - 6,25 = 8 5/10 + 5/6 - 6 25/100 = 8 150/300 + 250/300 - 75/300 = 8 325/300 = 9 25/300 = 9 1/12

3,5 + 5 1/7 - 2 3/14 = 3 5/10 + 5 1/7 - 2 3/14 = 3 35/70 + 5 10/70 - 2 15/70 = 6 30/70 = 6 3/7

7,6 - 4 2/3 + 2 1/15 = 7 6/10 - 4 2/3 + 2 1/15 = 5 40/30 = 5 4/3 = 6 1/3

2,25 + 11 1/15 - 7 1/6 = 2 25/100 + 11 1/15 - 7 1/6 = 6 145/300 = 6 29/60

6,8 - 2 1/3 + 1,12 = 6 8/10 - 2 1/3 + 1 2/10 = 5 40/30 = 6 10/30 = 6 1/3
