Question

【題目】用豎式計(jì)算小數(shù)除法時(shí),商的小數(shù)點(diǎn)要與（_____）的小數(shù)點(diǎn)對(duì)齊。

Answer 1

【答案】被除數(shù)

【解析】

除數(shù)是小數(shù)的小數(shù)除法法則：①先看除數(shù)中有幾位小數(shù)，就把被除數(shù)的小數(shù)點(diǎn)向右移動(dòng)幾位，數(shù)位不夠的用零補(bǔ)足；②然后按照除數(shù)是整數(shù)的小數(shù)除法來除：商的小數(shù)點(diǎn)要和被除數(shù)的小數(shù)點(diǎn)對(duì)齊；③如果除到被除數(shù)的末尾仍有余數(shù)，添0繼續(xù)除．此題主要考查對(duì)除數(shù)是小數(shù)的除法法則的理解．

解：計(jì)算小數(shù)除法時(shí)，商的小數(shù)點(diǎn)一定要與 被除數(shù)的小數(shù)點(diǎn)對(duì)齊．

故答案為：被除數(shù)．
