5.6*69.32+138.64*0.05+693.2*0.43（简算）

5.6*69.32+138.64*0.05+693.2*0.43（简算）
5.6*69.32+138.64*0.05+693.2*0.43
=5.6*69.32*+69.32*2*0.05+69.32*10*0.43
=69.32*(5.6+2*0.05+10*0.43)
=69.32*10
=693.2

6.932X56+6.932X1+6.932X43=6.932X(56+1+43)=6.932X100=693.2

=5.6x69.32+69.32X4.3+138.64x0.05
=5.6x69.32+69.32X4.3+69.32
=(5.6+4.3+1)x69.32
=10x69.32
=693.2
