3、没有相同的因数，不能使用乘法分配律。我们可以通过变一变，分一分的方法找出相同因数再运用乘法分配律进行计算 0.258.54 12.50.960.8 0.250.734 4.3612.58 0.2516.24 1.252.5323.20.2512.5 0.2536 (1.250.125)8 4.810.1 3.6102 0.39199 0.32403 3.6510.1 0.859.9 3.723.56.283.5 15.62.115.61.1 4.87.8780.52 56.59956.5 7.0910.80.87.09 1.879.90.187 4.2994.2 3.84.563.835.44
