7．除數(shù)是整數(shù)的小數(shù)除法，按照整數(shù)除法的法則計(jì)算，商的小數(shù)點(diǎn)要和被除數(shù)的小數(shù)點(diǎn)對(duì)齊，如果除到被除數(shù)的末尾仍有余數(shù)，就在余數(shù)的后面添零，再繼續(xù)除；除數(shù)是小數(shù)的除法，先運(yùn)用商不變規(guī)律把它轉(zhuǎn)化成除數(shù)是整數(shù)的除法，然后進(jìn)行計(jì)算．

Answer 1

分析 本題根據(jù)除數(shù)是整數(shù)或小數(shù)的小數(shù)除法運(yùn)算法則填空即可：
除數(shù)是整數(shù)的小數(shù)除法法則：（1）按照整數(shù)除法的法則去除，商的小數(shù)點(diǎn)要和被除數(shù)的小數(shù)點(diǎn)對(duì)齊；（2）如果除到被除數(shù)的末尾仍有余數(shù)，就在余數(shù)后面補(bǔ)零，再繼續(xù)除．
除數(shù)是小數(shù)的小數(shù)除法法則：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； 然后按照除數(shù)是整數(shù)的小數(shù)除法來(lái)除．

解答 解：除數(shù)是整數(shù)的小數(shù)除法，按照 整數(shù)除法的法則計(jì)算，商的小數(shù)點(diǎn)要和 被除數(shù)的小數(shù)點(diǎn)對(duì)齊，如果除到被除數(shù)的末尾仍有余數(shù)，就在余數(shù)的后面添 零，再繼續(xù)除；除數(shù)是小數(shù)的除法，先運(yùn)用商不變規(guī)律把它轉(zhuǎn)化成除數(shù)是整數(shù)的除法，然后進(jìn)行計(jì)算．
故答案為：整數(shù)，被除數(shù)，零，商不變規(guī)律．

點(diǎn)評(píng) 本題重點(diǎn)考查了學(xué)生對(duì)于小數(shù)除法運(yùn)算法則的理解．
