Question

5.6✖️47➕46✖️4.4简便算法？

Answer 1

简便方法如下：

1、提取原式：5.6✖️47➕46✖️4.4

2、计算过程：

   =5.6×47+47×4.4-4.4

   =47×( 5.6+4.4）-4.4

   =47×10-4.4

   =470-5+0.6

   =465+0.6

   =465.6

3、计算结果：465.6

4、谢谢，期待您的采纳。

Answer 2

因为5.6×47=5.6×（46+1）=5.6×46+4.6，所以原式等于5.6×46+4.6+46×4.4，运用乘法分配律逆运算可以得到46×（5.6+4.4）+4.6=460+4.6=464.6

Answer 3

5.6✖️47➕46✖️4.4
=5.6✖️（46+1）➕46✖️4.4
=5.6*46+5.6*1+46*4.4
=(5.6+4.4）*46+5.6
=46*10+5.6=465.6

Answer 4

5.6✖️47➕46✖️4.4
=5.6✖️46➕46✖️4.4+5.6
=46*（5.6+4.4）+5.6
=46*10+5.6
=465.6

Answer 5

5.6×47+46×4.4
=5.6×(46+1)+46×4.4
=5.6×46+5.6×1+46×4.4
=46×(5.6+4.4)+5.6
=46×10+5.6
=460+5.6
=465.6
