简便算法可以这样算，式子＝0.8×1.25×0.25×0.4=1×0.1=0.1。乘法的结合率运算简单=（0.8x1.25）x（0.25x0.4）=1x0.1=0.1 =8×125×25×4×0.000001=1000×100×0.00001=0.1 0.8×0.25×0.4×1.25的简便计算为：=（0.8x0.25）x（0.4x1.25）=0.2x0.5=0.1...
0.04×0.2×0.8×1.25×0.5×0.25的简便计算,是什么?= (0.04×0.25)×(0.2×0.5)×(0.8×1.25)= 0.01×0.1×1 = 0.001
0.8×0.25×0.4×1.25的简便计算?＝（0.25×0.4）×（0.8×1.25）＝0.1×1 ＝0.1
0.8x0.25x0.4x1.25怎么简便计算解:因为0.8ⅹ1.25=1，0.25ⅹ0.4=0.1，那么可以运用乘法结合律将0.8同1.25相乘，0.25同0.4相乘，然后将它们的积再相乘。计算过程 0.8ⅹ0.25ⅹ0.4ⅹ1.25 =(0.8ⅹ1.25)ⅹ(0.25x0.4)=1x0.1 =0.1。
1.25乘以0.25乘以0.4乘以0.8等于? 简便计算1.25乘0.8等于1 0.25乘0.4等于0.1然后1乘0.1就可以
1.25×1.2×4×0.8的简便方法计算?因为125×8=1000，所以运用乘法结合律改变运算顺序结果保持不变所以原式等于1.25×0.8×（1.2×4）=1×4.8=4.8
