Question

口算（最后兩題保留兩位小數(shù)）．

1.2×0.3=	9.1×0.91=	1.25×0.8=	0.73+0.7=
1.2÷0.3=	0.125÷0.04=	1.04×0.02=	1-0.11=
4.5×0.96=	5.01×0.6=	2.14×0.52≈	8÷1.04≈

Answer 1

考點(diǎn)：小數(shù)乘法,數(shù)的估算,小數(shù)除法

專題：計(jì)算題

分析：根據(jù)小數(shù)乘除法的計(jì)算方法計(jì)算即可．

解答：

解：1.2×0.3=0.36	9.1×0.91=8.281	1.25×0.8=1	0.73+0.7=1.43
1.2÷0.3=4	0.125÷0.04=3.125	1.04×0.02=0.0208	1-0.11=0.89
4.5×0.96=4.32	5.01×0.6=3.006	2.14×0.52≈1	8÷1.04≈8

點(diǎn)評：此題主要考查了學(xué)生根據(jù)小數(shù)乘除法的計(jì)算方法口算的能力，注意小數(shù)點(diǎn)的位置．
