2.01×8.53________8.53  
6.42÷1.03________6.42.

>    <
分析:(1)通過平常的計算我們可以總結規(guī)律:兩個數(shù)的積與其中一個因數(shù)比較,(兩個因數(shù)都不為0),要看另一個因數(shù);如果另一個因數(shù)大于1,則積大于這個因數(shù);如果另一個因數(shù)小于1,則積小于這個因數(shù);如果另一個因數(shù)等于1,則積等于這個因數(shù);由此規(guī)律解決問題.
(2)一個數(shù)除以大于1的數(shù),商小于這個數(shù),由此解答.
解答:(1)2.01×8.53>8.53;
(2)6.42÷1.03<6.42;
故答案為:>,<.
點評:這種題目從整數(shù)的乘除法到小數(shù)乘除法、分數(shù)乘除法都有滲透,做題時要靠平時的積累,不要單憑計算去判斷,要形成規(guī)律.
