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)84.810.13.61020.391990.324033.6510.10.859.93.723.56.283.5115.62.115.61.14.87.8780.5256.59956.57.0910.80.87.091.879.90.1874.2994.23.84.563.835.449.7999.727.53.77.53.73.140.6831.40.0327.20.22.41.45.411-5.47.74（2.81.3）1.52.263.92.73.97.312.79.91.2722.316+2.323+2.33.654.736.50.371010.87-0.91874657238610.716.1-15.110.77.60.80.27.61.288.60.728.610.60.359.60.358.91.010.65101480.56440.480.2793430.6572790.2645192640.4819.161.530.05391.60.1259612.510.8（204）0.2534521502.1451.585.515.8257.30.44
