Answer 1

考點(diǎn)：小數(shù)除法,小數(shù)乘法

專題：運(yùn)算順序及法則

分析：運(yùn)用小數(shù)加減及乘除法的計(jì)算法則進(jìn)行計(jì)算即可．

解答： 解：0.036×100=3.6
12.1÷1.1=11
0.45×10=4.5
9.6÷0.32=30
6+3.4=9.4
0.8+0.8÷0.8=1.8
0.24+0.76=1
1.5×0.2÷0.3=1
0.28÷0.01=28
10-0.1=9.9
4.3×0.2=0.86
2.25÷0.01=225

點(diǎn)評(píng)：計(jì)算時(shí)要認(rèn)真，注意除法計(jì)算結(jié)果小數(shù)點(diǎn)位置運(yùn)用被除數(shù)的小數(shù)點(diǎn)對(duì)齊，乘法中小數(shù)部分的小數(shù)位數(shù)，小數(shù)加減，小數(shù)點(diǎn)要對(duì)齊．
