Answer 1

1) = 4 11/12 + 8/12 - 3 7/12 + 1 11/12 = 4 19/12 + 1 11/12 - 3 7/12 = 
= 5 30/12 - 3 7/12 = 2 23/12 = 3 11/12 
2) = 7 5/18 - 3 7/18 - 5 11/18 + 2 13/18 = 9 18/18 - 8 18/18 = 1 
3) = 5/9 + 2 4/9 - 8/9 - 1 5/9 + 4 4/9 - 7/9 = 2 9/9 + 4 4/9 - 1 13/9 - 7/9 = 
= 6 13/9 - 1 13/9 - 7/9 = 5 - 7/9 = 4 9/9 - 7/9 = 4 2/9 
4) = 7 4/33 - 2 16/33 + 2 10/33 + 1 24/33 - 7 + 3 14/33 = 
= 9 14/33 + 4 38/33 - 9 16/33 = 13 52/33 - 9 16/33 = 4 36/33 = 5 3/33 =
= 5 1/11
