Answer 1

1) 7/9 +3 2/9 = 7/9 + 29/9 = 36/9 = 4

2) 9 - 5 1/4 = 36/4 - 21/4 = 15/4 = 3 3/4

3) 1 7/8 + 2 6/8 = 15/8 + 22/8 = 37/8 = 4 5/8

4) 4 5/7 - 1 6/7 = 33/7 - 13/7 = 20/7 = 2 6/7

5) 15 2/9 - (7 1/9 + 4 5/9) = 137/9 - (64/9 + 41/9) = 137/9 - 105/9 = 32/9 = 3 5/9

6) (2 5/7 + 8 2/7) - 4 7/8 = (19/7 + 58/7) - 39/8 = 77/7 - 39/8 = 11 - 39/8 =
    = 88/8 - 39/8 = 49/8 = 6 1/8

7) (4 2/5 + 3 4/5) - (12 - 8 1/5) = (22/5 + 19/5) - (60/5 - 41/5) = 41/5 - 19/5 = 22/5 =
    = 4 2/5

8) 12 6/11 - (5 4/11 + 6 9/11 - 2 3/11) = 138/11 - (59/11 + 75/11 - 25/11) =
    = 138/11 - 109/11 = 29/11 = 2 7/11
