68.8÷4=    85.44÷16=    67.5÷15   289.9÷18= 

101.7÷9=    243.2÷64=   16.8÷28=   15.6÷24=

10÷25    2.7÷7.5=    15÷0.06=    25.6÷0.032=  

14.36÷2.7≈    8.33÷6.2≈    1.7÷0.03≈   32÷42≈  

1.25÷1.2≈    2.41÷0.7 4.5×0.07= 6.3÷0.09=

45×2.46= 3.6÷0.24= 382.5÷45= 6.4×5.48=

13.42×4.73 = 9.65×8.12 = 7.23×1.2 = 6.3×12 =

2.14×8.3 = 4.9×1.12 = 21.98×2.31 = 0.24×28.37 =

29.13×3.14 = 9.88×11.21 = 5.5÷11 = 7.5÷0.5 =

6÷1.2 = 3.2÷8 = 7.2÷0.9 = 24÷1.2 =

5.26÷1.6 = 0.85×6.3  =            52.6×0.252=             35÷73 =   

 4、判断。

1)如果两个因数的积不是小数,那么这两个因数一定不是小数。(  

2)一个不等于0的数的1.02倍一定比原数大。      

3)因为12×35=420,所以1.2×3.5=42.    

4)在表示近似数时,5.0也可以写成5。(   

5)整数乘法的交换律、结合律和分配律,对于小数乘法同样适用。( 

60.25×9.9=0.25×10-1=0.25×10-0.25。(   

74.104.1大小相等,表示意义也相同。(  

83.994精确到百分位约是4.00.   

9)一个数(0除外)除以小数,商一定比这个数大。(    

10)两个数相除的商是0.9,被除数不变,除数扩大10倍,商是9.  

5、把下列各式中的乘积点上小数点,使等式成立。

   9.36×2.7=25272             0.89×6.43=57227
