Решите примеры 1)4 целых 8/11 - (5 целых 2/11 - 3 целых 7/11) 2) 16 целых 10/11 - (1 целая 4/11 + 7 целых 9/11) 3) 1 целая 5/9 + 6/9 .

4 8/11-(5 2/11 - 3 7/11)=4 8/11-1 6/11=3 2/11

16 10/11-(1 4/11 + 7 9/11)=16 10/11- 9 2/11= 7 8/11

1 5/9+ 6/9=2 2/9

1 5/9+6/9=1 11/9=2 2/9

16 10/11-(1 4/11+7 9/11)=16 10/11-8 13/11=16 10/11-9 2/11=7 8/11

4 8/11-(5 2/11-3 7/11)=4 8/11-1 6/11=3 2/11
