Question

看谁算行又对又快 0.45÷0.05=	4.3×0.5=	1-0.08=	600×0.01=
0.65×1.02=	7206÷0.6=	2.5+2.5×3=	1.25×0.8×0.4=
1÷0.1-1×0.1=	5.3×0.3+4.7×0.3=	630÷5÷0.6=	0.25×4÷0.25×4=

Answer 1

分析：根据小数加减乘除的计算方法进行计算，2.5+2.5×3根据乘法分配律，5.3×0.3+4.7×0.3根据乘法分配律，630÷5÷0.6根据除法的性质简便计算．

解答：解：

0.45÷0.05=9	4.3×0.5=2.15	1-0.08=0.92	600×0.01=6
0.65×1.02=0.663	7206÷0.6=12010	2.5+2.5×3=10	1.25×0.8×0.4=0.4
1÷0.1-1×0.1=9.9	5.3×0.3+4.7×0.3=3	630÷5÷0.6=210	0.25×4÷0.25×4=16

点评：此题主要考查了小数四则混合运算的运算顺序和运算法则．
