Answer 2

这道题的简便计算方法是：50.4*1.9-1.8=50.4（2-0.1）-1.8=100.8-（5.04+1.8）=100.8-6.84=93.96。

Answer 3

简算：
原式=50.4×1.9-1.8
=50.4×（2-0.1）-1.8
=100.8-5.04-1.8
=100.8-1.8-5.04
=99-5.04
=93.96
运用了乘法分配律和减法结合律

Answer 4

50.4×1.9-1.8
＝50×1.9+0.4×1.9-1.8
＝95+0.76-1.8
＝93.96

Answer 5

50.4×1.9-1.8
=95.76-1.8
=93.96
