Question

6．請(qǐng)直接寫出得數(shù)

0.07×0.8=	1.7×0.03=	0.16×0.5=	4.5×0.03=	0.72÷12=
5.2÷13=	0.7×1.1=	9.6÷0.6=	0÷3.68=	0.48÷0.03=
2.5×3.6×8=	2.33×0.2×5=	2.5×6-2.5=	0.7×16-16×0.3=	0.9÷0.3÷0.3=

Answer 1

分析 根據(jù)小數(shù)加減乘除法的計(jì)算方法進(jìn)行計(jì)算即可；
2.5×3.6×8根據(jù)除法交換律進(jìn)行計(jì)算即可；
2.33×0.2×5根據(jù)乘法結(jié)合律進(jìn)行計(jì)算即可；
2.5×6-2.5、0.7×16-16×0.3根據(jù)乘法分配律進(jìn)行計(jì)算即可；
0.9÷0.3÷0.3根據(jù)除法的性質(zhì)進(jìn)行計(jì)算即可．

解答 解：

0.07×0.8=0.056	1.7×0.03=0.051	0.16×0.5=0.08	4.5×0.03=0.135	0.72÷12=0.06
5.2÷13=0.4	0.7×1.1=0.77	9.6÷0.6=16	0÷3.68=0	0.48÷0.03=16
2.5×3.6×8=72	2.33×0.2×5=2.33	2.5×6-2.5=12.5	0.7×16-16×0.3=6.4	0.9÷0.3÷0.3=10

點(diǎn)評(píng) 考查了小數(shù)加減乘除法的口算能力，按照各自的計(jì)算方法進(jìn)行計(jì)算即可．
