Question

2.4÷3=	5.2÷1.3=	6.6÷0.3=
6.3÷0.09=	1.8÷2=	7.2÷1.2=
2.5÷0.5=	1.5÷0.25=	3.2÷4=
5.6÷1.4=	9.6÷3.2=	0.64÷1.6=

Answer 1

分析：除數(shù)是小數(shù)的除法：先把除數(shù)轉(zhuǎn)化為整數(shù)，除數(shù)的小數(shù)點(diǎn)向右移動(dòng)幾位，就把被除數(shù)的小數(shù)點(diǎn)相應(yīng)的向右移動(dòng)幾位，數(shù)位不夠的用0補(bǔ)足，然后按照除數(shù)是整數(shù)的小數(shù)除法的法則計(jì)算．

解答：

解：2.4÷3=0.8	5.2÷1.3=4	6.6÷0.3=22
6.3÷0.09=70	1.8÷2=0.9	7.2÷1.2=6
2.5÷0.5=5	1.5÷0.25=6	3.2÷4=0.8
5.6÷1.4=4	9.6÷3.2=3	0.64÷1.6=0.4

點(diǎn)評(píng)：此題考查小數(shù)除法計(jì)算方法的運(yùn)用，計(jì)算時(shí)要細(xì)心，注意除數(shù)和被除數(shù)小數(shù)點(diǎn)的變化．
