1.
3/8 + 2 5/(8 )+ 1 7/8 = 4 7/8
2.
2.1 1/5 + 4 5/6 = 1 5/30 + 4 25/30 = 6
3. 3 7/8 + (5 1/6 + 4 4/6) = 3 7/8 + 9 5/6 = 3 21/24 + 9 20/24 = 13 17/24
4.
4 16/9 - 3 8/9 = 1 8/9
5.
5 8/24 - 3 15/24 = 1 17/24
6.
6 7/9 - (4 2/6 + 1 3/6) = 6 7/9 - 5 5/6 = 6 42/54 - 5 45/54 = 51/54 = 17/18

3/8 + 21/8 + 15/8 = 32/8 =4
6/5 + 29/6 = 36/30 + 145/30 = 6 i 1/30
31/8 + (31/6 -14/3) = 31/8 - 1/2 = 27/8 = 3 i 3/8
52/9 - 35/9 = 17/9 = 1 i 8/9
16/3 - 29/8 = 128/24 - 87/24 = 41/24 = 1 i 17/24
61/9 - (13/3 + 4/2) = 61/9 - 13/6 = 122/18 - 39/18 = 83/18 = 5 i 1/18
