7×0.5= | 4÷0.8= | 5.6-2.3= | 0.125×4= | 44÷1.2= | 3.2÷1= |
3.07×100= | 1.8×5= | 36÷3.6= | 9.6÷1.2= | 0÷0.9= | 0.1×0.12= |
5÷0.3×0.2= | 12.5+12.5÷12.5= | 0.6+0.6÷0.6-0.6= | 2×0.7+4.2×0.3= | (8.5-1.5)÷0.1= | 20-3.7-6.3= |
分析:本题根据小数乘除法的计算法则求解;
5÷0.3×0.2按照从左到右的顺序求解;
12.5+12.5÷12.5先算乘法,再算加法;
0.6+0.6÷0.6-0.6先算除法,再算加法,最后算减法;
2×0.7+4.2×0.3同时运算两个乘法,再算加法;
(8.5-1.5)÷0.1先算小括号里面的减法,再算括号外的除法;
20-3.7-6.3根据减法的性质简算.
