小數(shù)除小數(shù),商一定是小數(shù).
錯誤
分析:小數(shù)除小數(shù),如果將除數(shù)小數(shù)點去掉后,除數(shù)能整除被除數(shù),則商為整數(shù),如:0.2÷0.05=20÷5=4;如果將除數(shù)小數(shù)點去掉后,除數(shù)不能整除被除數(shù),則商為小數(shù),如:0.2÷0.5=0.4.
解答:在小數(shù)除法中,小數(shù)除小數(shù),商不一定是小數(shù).
如果將除數(shù)小數(shù)點去掉后,除數(shù)不能整除被除數(shù),則商為小數(shù),如:0.2÷0.5=0.4.
故答案為:錯誤.
點評:本題舉例解答更直觀一些.
