4.6*5.6+0.56*54怎么简便？

Question

如题所述

Answer 1

可以把它化简成。4.6×5.6+5.6×5.4。这时候可以合并同类项，就会变成5.6×（4.6+5.4）。然而最终的结果就会变成56的。

Answer 2

4.6x5.6+0.56x54
=4.6x5.6+0.56x5.4x10
=4.6x5.6+0.56x10x5.4
=4.6x5.6+5.6x5.4
=5.6x（4.6+5.4）
=5.6x10
=56本回答被网友采纳

Answer 3

6×5.5 =4.6×（15.5-5.5）=4.6×10 =46 简便计算方法就是把0.46变成4.6，然后提取公因数4.6，这样就简便了。

Answer 4

4.6×5.6+0.56×54这么简便：
4.6×5.6+0.56×54=4.6×5.6+5.6×5.4
=5.6(4.6+5.4)
=5.6×10
=56
