1、直接写出得数。
1.25×8= 3.08×0.01= 4.95×1000= 6.9×0.1= 0.4×0.5=
2.4÷0.8= 10.8÷9= 9.6÷0.8= 0.108÷2= 3.6÷10=
6.3＋0.37= 2.6÷0.02= 0.11×5= 4.8÷4=
2.5-2.5÷5=
1.12×0.3= 0.8×0.5= 0÷7.05= 1.5×30=
3.5＋6.5×20=
1.25×4= 9.6÷10= 6.3＋3.37= 3.6÷0.3= 0.71×5=
4.8÷6= 0.25×8= 1.82×0.3= 0.28×0.5= 0.42÷0.7=
7.5×30= 0.4×5= 4.2÷0.2= 4.2-1.6= 21.7÷0.07=
1.6×7= 25.25÷5= 1.45×8= 60×0.9= 0.8×0.1=
0.4×2.5= 0.32×5= 1.8×20= 0.01÷0.1=
1.7＋3.3×0.2=
1.8÷0.3= 3.2-0.1= 0.27÷0.03= 6.5×10= 80×0.3=
2、用竖式计算：
0.59×0.027＝
6.72÷6.4＝
9.8×3.7=
1.03×5.9＝
0.44×2.5=
3、脱式计算，能简便的用简便方法计算。
1.87×3.05＋8.13×3.05
1.25×0.45×0.8
2.25×0.4 0.6
31.04÷3.2－4.7
1.39×6.1＋3.9×1.39
