9 11/18 - 5 3/4 -1 15/36 + 2 7/9;
5 5/8 +8 3/4 - 6 1/5 +3

Answer 1

9 11/18 - 5 3/4 - 1 15/36 + 2 7/9 = 9 22/36 - 5 27/36 + 1 15/36 + 2 28/36 =
= (9 22/36 + 1 15/36 + 2 28/36) - 5 27/36 = 13 29/36 - 5 27/36 = 8 2/36 = 8 1/18

5 5/8 + 8 3/4 - 6 1/5 + 3 = 5 25/40 + 8 30/40 - 6 8/40 + 3 = (5 25/40 + 8 30/40 + 3) - 6 8/40 = 17 15/40 - 6 8/40 = 11 7/40
