0.62乘以3.2加6.2乘以0.32简便运算怎么做？

Answer 1

这是小学数学关于乘法分配律扩大逆运用进行简便运算的问题。即:0.62ⅹ3.2+6.2ⅹ0.32=6.2ⅹ0.32+6.2ⅹ0.32=（6.2+6.2）ⅹ0.32=13.4ⅹ0.32=4.288

Answer 2

0.62＊3.2+6.2＊0.32
=6.2＊（0.32+0.32）
=6.2＊0.64
=0.64＊（6+0.2）
=3.84+0.128
=3.968

Answer 3

你好，0.62×3.2+6.2×0.32可以写成0.62×3.2+0.62×3.2即两个0.62×3.2，所以0.62×3.2×2=3.968。

Answer 4

0.62乘以3.2加6.2乘以0.32简便运算怎么做？
=0.62×3.2+6.2×0.32
=6.2×0.32+6.2×0.32
=6.2×（0.32+0.32）
=6.2×0.64
=3.968
望采纳 谢谢~~

Answer 5

根据题意列出以下步骤：
0.62x3.2+6.2x0.32

=0.62x3.2+6.2÷10x0.32

=0.62x3.2+0.62x0.32

=2x0.62x3.2
=1.24x3.2

=(1.25-0.01)x3.2

=1.25x3.2-0.01x3.2

=1.25x8x0.4-0.01x3.2

=4-0.032

=3.968
以上是计算过程，得数是3.968。
