Answer 1

-7 4/9 - 2 1/6 = -7 8/18 - 2 3/18 = -11 11/18
3 1/4 - 8 5/6 = 13/4 - 53/6 = 39/12 - 106/12 = - 67/12 = - 5 7/12
- 2 3/5 + 7 1/3 = - 2 9/15 + 7 5/15 = - 39/15 + 110/15 = 71/15 = 4 11/15
- 3,12 - 6,1 = - 9,22
- 7,2 + 12,36 = 5,16
6,4 - 10,25 = - 3,85
- 3 1/7 - 1,2 = - 3 1/7 - 6/5 = -22/7 - 6/5 = - 110/35 - 42/35 = - 152/35 = - 4 12/35
4 5/6 - 8,2 = 29/6 - 41/5 = 145/30 - 246/30 = - 101/30 = - 3 11/30
- 5,65 + (-2,08) - 1,35 = -5,65 - 2,08 - 1,35 = - 9,08
6,51 + (-2,775) - 11,125 = 6,51 - 2,775 - 11,125 = - 7,39

-10/9 + (-1/6) + 9 3/4 - 6,25 = -10/9 - 1/6 + 39/4 - 25/4 = -40/36 - 6/36 + 351/36 - 225/36 = 80/36 = 2 8/36 = 2 2/9
-9,3 - (-12 1/5) - (72,8-(-13,002)) = -9,3+12,2-72,8-13,002 = -82,902
