Question

直接寫(xiě)得數(shù)． 0.45÷9=	0.01+0.99=	1÷0.01=
5.2÷5.2=	3.126×100=	3a+2a=
1.25×8=	4.2÷1.4=	10-5.6=
9.62-4.6=	0.6×0.4=	6m-m=

Answer 1

考點(diǎn)：小數(shù)除法,小數(shù)的加法和減法,小數(shù)乘法

專(zhuān)題：計(jì)算題

分析：根據(jù)四則運(yùn)算的計(jì)算法則計(jì)算即可求解．

解答： 解：

0.45÷9=0.05	0.01+0.99=1	1÷0.01=100
5.2÷5.2=1	3.126×100=312.6	3a+2a=5a
1.25×8=10	4.2÷1.4=3	10-5.6=4.4
9.62-4.6=5.02	0.6×0.4=0.24	6m-m=5m

點(diǎn)評(píng)：考查了四則運(yùn)算，關(guān)鍵是熟練掌握計(jì)算法則正確進(jìn)行計(jì)算．
