3. 4  1/6 - 2 5/6 = 25/6 - 17/6 = 8/6 = 1 2/6= 1 1/3

4. 1 5/9 + 2 1/3 + 3 1/6 = 1 5/9 + 2 3/9 + 3 1/6 = 3 8/9 + 3 1/6 = 3 16/18 + 3 3/18 = 6 19/18 = 7 1/18

5. 4 5/6 +1 1/6 + 2 3/6 = 7 9/6 = 8 3/6 = 8 1/2

8. 4 1/6 - 1 3/5 + 2 1/2 = 4 5/30 - 1 18/30 + 2 15/30 = 4 5/30 - 3 33/30 = 125/30 - 123/30 = - 2/30 = - 1/15

9. 4 1/2 - 2 3/5 - 1 2/3 = 4 5/10 - 2 6/10 - 1 2/3 = 45/10 - 26/10 - 1 2/3 = 19/10 - 1 2/3 = 1 9/10 - 1 2/3 = 1 27/30 - 1 20/30 = 7/30
