Question

用豎式計(jì)算． 32.2÷14	0.4×29	0.864÷24
24×8.5	5.55÷37	24×0.45

Answer 1

分析：①③⑤運(yùn)用小數(shù)除法的計(jì)算法則進(jìn)行計(jì)算，商的小數(shù)點(diǎn)與被除數(shù)的小數(shù)點(diǎn)對(duì)齊；②④⑥運(yùn)用小數(shù)的乘法的計(jì)算法則進(jìn)行計(jì)算．

解答：解：①32.2÷14=2.3

②0.4×29=11.6

③0.864÷24=0.036

④24×8.5=204

⑤5.55÷37=0.15

⑥24×0.45=10.8
．

點(diǎn)評(píng)：本題考查了小數(shù)的乘除法，運(yùn)用小數(shù)乘除法的計(jì)算法則進(jìn)行計(jì)算，注意正確確定小數(shù)的位數(shù)以及小數(shù)點(diǎn)的位置．
