Question

【題目】列豎式計算小數(shù)除法時，商的小數(shù)點一定要與　　　　　　的小數(shù)點對齊．

Answer 1

【答案】被除數(shù)．

【解析】

試題分析：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)點向右移動幾位，數(shù)位不夠的用零補足； （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)點要和被除數(shù)的小數(shù)點對齊；（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：計算時，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)點向右移動幾位，數(shù)位不夠的用零補足，然后按照除數(shù)是整數(shù)的小數(shù)除法來除，商的小數(shù)點要和被除數(shù)的小數(shù)點對齊．

故答案為：被除數(shù)．
