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。
(6)0.25×
9.9=0.25×
(10-1)=0.25×
10-0.25。
(7)4.10与4.1大小相等,表示意义也相同。
(8)3.994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。
