Question

6.42ⅹ4.6+5.1ⅹ6.42简算？

Answer 1

6.42Ⅹ4.6+5.1X6.42
=6.42ⅹ（4.6+5.1）
=6.42X9.7
=6.42X（10－0.3）
=6.42X10－6.42x0.3
=64.2－1.926
=62.274

Answer 2

6.42×4.6+5.1×6.42简算：
6.42×4.6+5.1×6.42
=6.42×(4.6+5.1)
=6.42×9.7
=6.42×(10-0.3)
=64.2-19.26
=44.94
希望能帮到你。

Answer 3

简便算法：
6.42*4.6+5.1*6.42
=（4.6+5.1）*6.42
=9.7*6.42
=62.274

Answer 4

你好，你提得这个问题是一道简单的小学数学题
这道题主要考查简便方法的计算
这道题的解法是
6.42*4.6+5.1*6.42
=6.42*(4.6+5.1)
=6.42*9.7
=6.42*(10-0.3)
=6.42*10-6.42*0.3
=64.2-1.926
=62.274
希望帮到你，望采纳

Answer 5

这道题目其实通过观察就可以得到两边的式子里都有一个6.42，所以可以把6.42作为公因数提出来。题目就变成了6.42×（4.6+5.1）=62.274
