Question

計(jì)算小數(shù)除法時(shí)，商的小數(shù)點(diǎn)要與被除數(shù)的小數(shù)點(diǎn)對齊．

正確

．

Answer 1

分析：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)對齊；（2）如果除到被除數(shù)的末尾仍有余數(shù)，添0繼續(xù)除．

解答：解：根據(jù)小數(shù)除法法則：計(jì)算時(shí)，把除數(shù)變成整數(shù)，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)除法來除，
商的小數(shù)點(diǎn)要和被除數(shù)的小數(shù)點(diǎn)對齊．
所以說計(jì)算小數(shù)除法時(shí)，商的小數(shù)點(diǎn)要與被除數(shù)的小數(shù)點(diǎn)對齊，是正確的．
故答案為：正確．

點(diǎn)評：此題主要考查對除數(shù)是小數(shù)的除法法則的理解．
