5.6×69.32＋138.64×0.05＋693.2×0.43
=5.6×69.32+69.32*2*0.05+693.2*0.1*10*0.43
=5.6×69.32+69.32*0.1+69.32*4.3
=69.32*(5.6+0.1+4.3)
=69.32*10
=693.2

=5.6*69.32+138.64*0.05+69.32*4.3
=9.9*69.32+69.32*0.1
=69.32*10
=693.2

69.2×2＝138.64, 138.64 × 5＝693.2，后面自己算了

5.6×69.32＋138.64×0.05＋693.2×0.43
=5.6*69.32+69.34*2*0.05+69.32*4.3
=69.32*(5.6+0.1+4.3)
=69.32*1 0
=693.2

=5.6*69.32+138.64*0.05+69.32*4.3
=9.9*69.32+69.32*0.1
=69.32*10
=693.2
