6.7+3=	7-0.82=	13.5-6.2-3.8=	0.95÷5=
1.6×0.25=	0.1÷0.5=	3.5×2×0.1=	2.1÷0.2÷3.5=

Answer 1

考點：小數(shù)乘法,小數(shù)除法

專題：運算順序及法則

分析：根據(jù)小數(shù)加減乘除法的計算方法解答即可．

解答： 解：

0.25×3=0.75	9.1÷1.3=7	0.56×100=56	4.5÷0.9=5
6.7+3=9.7	7-0.82=6.18	13.5-6.2-3.8=3.5	0.95÷5=0.19
1.6×0.25=0.4	0.1÷0.5=0.2	3.5×2×0.1=0.7	2.1÷0.2÷3.5=3

點評：口算時，注意數(shù)據(jù)特點和運算符號，細(xì)心解答即可．
