Answer 2

1) 4 + 5/18 - 2 + 5/9 = 4 - 2 + 5/18 + 5/9 = 2 + 10/18 + 10/18 = 2 + 20/18 = 2 + 10/9 = 2 10/9

2) 16 + 4/9 - 1 + 7/9 = 16 - 1 + 4/9 + 7/9 = 15 + 11/9 = 15 11/9

3) 8 + 6/25 - 3 + 4/5 = 8 - 3 + 6/25 + 4/5 = 5 + 6/25 + 20/25 = 5 + 26/25 = 5 26/25

4) 5 + 13/15 - 4 + 7/30 = 5 - 4 + 13/15 + 7/30 = 1 + 26/30 + 14/30 = 1 + 40/30 = 1 10/30 = 1 1/3

5) 12 + 2/15 - 2 + 1/5 = 12 - 2 + 2/15 + 1/5 = 10 + 2/15 + 3/15 = 10 + 5/15 = 10 + 1/3 = 10 1/3

6) 7 + 4/13 - 6 + 3/26 = 7 - 6 + 4/13 + 3/26 = 1 + 8/26 + 3/26 = 1 + 11/26

7) 9 + 12/18 - 2 + 6/9 = 9 - 2 + 12/18 + 6/9 = 7 + 2/18 + 12/18 = 7 + 14/18 = 7 + 7/9 = 7 7/9

8) 3 + 3/8 + 1 + 1/8 = 3 + 1 + 3/8 + 1/8 = 4 + 4/8 = 4 + 1/2 = 4 1/2

9) 5 + 10/15 - 5 + 2/5 = 5 - 5 + 10/15 + 2/5 = 0 + 2/3 + 2/5 = 2/3 + 2/5 = (10/15) + (6/15) = 16/15 = 1 1/15

10) 2 + 3/5 + 10 + 2/5 = 2 + 10 + 3/5 + 2/5 = 12 + 5/5 + 2/5 = 12 + 7/5 = 12 + 1 2/5 = 13 2/5
