5.6X69.32+138.64X0.05+693.2X0.43简算写主要过程
答
5.6X69.32+138.64X0.05+693.2X0.43
=5.6×69.32+69.32×4.3+138.64×0.05
=(5.6+4.3)×69.32+69.32×2×0.05
=10×69.32+69.32+0.1
=693.2+6.932
=693.2+6.8+0.132
=700+0.132
=700.1325.6x69.32+138.64x0.05+693.2x0.43=5.6x69.32+69.32x2x0.05+69.32x10x0.43=69.32x(5.6+2x0.05+10x0.43)=69.32x10=693.2我找到答案了，是这个晕，我看错了，更正如下： 5.6X69.32+138.64X0.05+693.2X0.43 =5.6×69.32+69.32×4.3+138.64×0.05 =(5.6+4.3)×69.32+69.32×2×0.05 =9.9×69.32+69.32×0.1 =(9.9+0.1)×69.32 =10×69.32 =693.2 还好你没被误导，抱歉了。
