Question

6．直接寫出下面各題的得數(shù)．

5.4×0.01=	0.125×0.8=	0.27÷0.03=	1.8÷0.3=
500×0.2=	0.56÷0.4=	0.01÷0.1=	0.55÷0.11=
0.3×0.2=	2.4×10=	4.2÷0.7=	3.6÷12=
1.2×5=	9.1÷0.7=	15×0.6=	0.8-0.35=
7.5÷0.15=	1.25×17×0.8=	0.37×0÷9.54=	2-0.9+0.1=

Answer 1

分析 根據(jù)小數(shù)加減乘除的計算方法進行計算即可．

解答 解：

5.4×0.01=0.054	0.125×0.8=0.1	0.27÷0.03=9	1.8÷0.3=6
500×0.2=100	0.56÷0.4=1.4	0.01÷0.1=0.1	0.55÷0.11=5
0.3×0.2=0.06	2.4×10=24	4.2÷0.7=6	3.6÷12=0.3
1.2×5=6	9.1÷0.7=13	15×0.6=9	0.8-0.35=0.45
7.5÷0.15=50	1.25×17×0.8=17	0.37×0÷9.54=0	2-0.9+0.1=1.2

點評 口算時，注意運算符號和數(shù)據(jù)，然后再進一步計算即可．
