Question

計(jì)算除數(shù)是小數(shù)的除法，必須把被除數(shù)和除數(shù)都轉(zhuǎn)化成整數(shù)，才能計(jì)算．

錯(cuò)誤

．（判斷對(duì)錯(cuò)）

Answer 1

分析：根據(jù)除數(shù)是小數(shù)的除法法則可知，一個(gè)數(shù)除以小數(shù)，可以先將除數(shù)化為整數(shù)，再看除數(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)也向右移動(dòng)幾位．因此只要將除數(shù)化為整數(shù)即可．

解答：解：計(jì)算除數(shù)是小數(shù)的除法，只要將除數(shù)化為整數(shù)后，根據(jù)除數(shù)的小數(shù)點(diǎn)向右移動(dòng)的位數(shù)，被除數(shù)的小數(shù)點(diǎn)也向右移動(dòng)幾位，但此時(shí)被除數(shù)不一定為整數(shù)．
因此題目中的說(shuō)法是錯(cuò)誤的．
故答案為：錯(cuò)誤．

點(diǎn)評(píng)：本題考查了學(xué)生對(duì)于除數(shù)是小數(shù)的小數(shù)除法法則的理解．
