整數(shù)

；除數(shù)的小數(shù)點(diǎn)向右移動(dòng)了

幾位

；被除數(shù)的小數(shù)點(diǎn)也要向右

移動(dòng)

幾位．商的

小數(shù)點(diǎn)

要與被除數(shù)的小數(shù)點(diǎn)

對(duì)齊

．

Answer 1

分析：本題根據(jù)除數(shù)是小數(shù)的小數(shù)除法的運(yùn)算法則分析填空即可．

解答：解：小數(shù)除法，要先將除數(shù)是小數(shù)的改寫成 整數(shù)；
除數(shù)的小數(shù)點(diǎn)向右移動(dòng)了 幾位；
被除數(shù)的小數(shù)點(diǎn)也要向右 移動(dòng)幾位．商的 小數(shù)點(diǎn)要與被除數(shù)的小數(shù)點(diǎn) 對(duì)齊．
故答案為：整數(shù)，幾位，移動(dòng)，小數(shù)點(diǎn)，對(duì)齊．

點(diǎn)評(píng)：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)除法來除．
