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
