6.15×9.4-9.6×4.15
=6.15×9.4 - (9.4+0.2)×4.15
=6.15×9.4-9.4×4.15-0.2×4.15
=9.4×(6.15-4.15) - 0.83
=9.4×2 - 0.83
=18.8 - 0.83
= 17.97
=6.15×9.4 - (9.4+0.2)×4.15
=6.15×9.4-9.4×4.15-0.2×4.15
=9.4×(6.15-4.15) - 0.83
=9.4×2 - 0.83
=18.8 - 0.83
= 17.97

可以这样计算
6.15*9.4-9.6*4.15
=6.15*9.6-6.15*0.2-9.6*4.15
=9.6*(6.15-4.15)-6.15*0.2
=9.6*2-6.15*0.2
=19.2-1.23
=17.97本回答被网友采纳
6.15*9.4-9.6*4.15
