Answer 2

1) 8.3 + (9.5 - 10.3) = 8.3 + (-0.8) = 7.5

2) 0.2 + (4.8 - 6 1/8) = 0.2 + (4.8 - 49/8) = 0.2 + (4.8 - 6.125) = 0.2 + (-1.325) = -1.125

3) (3 1/2 + 2 1/9) + 3 1/9 + 4 = (7/2 + 19/9) + 28/9 + 4 = (63/18 + 38/18) + 28/9 + 4 = (101/18) + 28/9 + 4 = (101/18) + (56/18) + 4 = 157/18 + 4 = 157/18 + 72/18 = 229/18 = 12 11/18

4) -0.6 + (-4.4 + 3.8) = -0.6 + (-0.6) = -1.2

5) -1.8 - (-4.8 + 2.9) = -1.8 - (-1.9) = -1.8 + 1.9 = 0.1
