1、实用文档之小数乘法简便计算练习题小数乘法的简便计算的方法：1、分析算式的结构：（1）连乘，考虑乘法交换律和结合律；（2、）乘加或乘减，考虑乘法分配律。2、当结构不完整时，我们可以通过变式、拆分的方法，让算式变成符合运算律的形式，再进行简算。3、注意：口算要准确。0.258.5412.50.960.80.250.7344.3612.580.2516.241.252.5323.20.2512.50.2536(1.250.125)84.810.13.61020.391990.324033.6510.10.859.93.723.56.283.5115.62.115.61.14.87.8780.5256
