一、直接写出得数。
1.48 + 0.22 = 5.6 - 2.3 = 8.2 + 0.72 =
1 - 0.43 = 8.02 + 2.16 = 0.89 - 0.005 =
2.32 + 0.4 = 12.7 - 3 = 9.8 + 0.02 =
3.6 + 0.36 = 5.43 + 1.47 = 5 - 3.28 =
0.7 - 0.12 = 8.1 - 2.2 = 6.8 + 8.6 =
4.3 + 1.7 = 0.56 + 0.44 = 3.03 - 2.4 =
0.26 + 0.48 = 8.5 - 3.68 = 0.97 + 0.2 =
7.2 - 2.08 = 3.6 + 7.75 = 9.25 - 1.39 =
0.27 + 0.73 = 4.5 - 2.6 = 10 - 2.5 =
5.1 - 1.46 = 12.47 + 10.8 = 6 + 0.095 =

二、计算下面各题。
12.7 + 4.59 - 3.6 17.37 -（3.6 + 8.44） 4.8 + 42.27 - 16.8

答案： 13.69 5.33 30.27
