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
=700.132追问5.6x69.32+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，是这个追答晕，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。
