一、直接写出得数。(每题1分，共30分)
1.8 + 0.3 = 0.12×4 = 12 - 0.35 =
5.5×2 = 0.63 - 0.45 = 7.2 + 0.26 =
1.2 - 0.04 = 1.42 + 0.27 = 1.5×10 =
5.6÷10 = 2.5×0.2 = 8.2 - 3.5 =
0.66×0.5 = 9.6 - 4.5 = 0.36 + 0.44 =
5.8 - 5 = 0.74 + 0.26 = 0.17×30 =
0.9 + 0.8 = 0.65×0.1 = 12.4÷1000 =
4.6 - 0.06 = 0.58 + 1.3 = 0.98×100 =
6.3 + 0.7 = 0.4×0.8 = 5.3 - 2.45 =
0.18×20 = 1.05 - 0.95 = 7.42 + 4.58 =
