一、直接写出得数
1.5×4=
5.8+1.2=
45×0.2=
4.08÷8=
0.54÷0.6=
3.1-2.9=
0.12÷3=
0.4×0.7=
0.32×1000=
7÷100=
0.8+0.02=
0.84÷0.3=
3.68÷0.01=
9+1.5=
0.4×0.5=
0.44+0.6=
2.5×0.4=
0.125×8=
3.6÷0.4=
3.92+7.2=
二、竖式计算。
(1)7.6×0.9
(2)10.5×0.
3
(3)4.25×0.18
(4)
0.3÷0.12
(5)104.78÷26
(6)
34.2÷0.8
三、脱式计算,能简算的要简算。
8.7×10.1
7.06×2.4-5.7
6.35÷0.8÷1.25
2.5×6.8×0.4
2.5×3.2×1.25
21.36÷0.8×2.9
102×0.45
8.27+7.52+1.73-3.52
0.79×99+0.79
0.15+
0.75×18
72+8÷2.5-30.2
2.8×3.2+3.2×7.2
