Question

計(jì)算小數(shù)除法時(shí)，商的小數(shù)點(diǎn)要與變化后被除數(shù)的小數(shù)點(diǎn)對(duì)齊．

√

．（判斷對(duì)錯(cuò)）

Answer 1

分析：根據(jù)小數(shù)除法的計(jì)算法則，首先移動(dòng)除數(shù)的小數(shù)點(diǎn)，使它變成整數(shù)，除數(shù)的小數(shù)點(diǎn)向右移動(dòng)幾位，被除數(shù)的小數(shù)點(diǎn)也向右移動(dòng)相同的位數(shù)，然后按照除數(shù)是整數(shù)的除法法則計(jì)算，商的小數(shù)點(diǎn)要與被除數(shù)的小數(shù)點(diǎn)對(duì)齊．據(jù)此判斷．

解答：解：根據(jù)分析知，計(jì)算小數(shù)除法，商的小數(shù)點(diǎn)要與變化后被除數(shù)的小數(shù)點(diǎn)對(duì)齊．
故答案為：√．

點(diǎn)評(píng)：此題考查的目的是理解掌握小數(shù)除法的計(jì)算法則．
