Question

6.4÷12.5x8该怎么简算啊？

Answer 1

6.4÷12.5x8
=6.4x8/12.5
【分子分母同乘以0.8】
=6.4x6.4/10
=6.4²/10
=(6+0.4)²/10
=(36+4.8+0.16)/10
=40.96/10
=4.096

Answer 2

6.4÷12.5x8
二0.512x8
二4.096

Answer 3

6.4÷12.5x8该这么简算：
6.4÷12.5x8=6.4x8÷12.5
=51.2÷12.5
=4.096

Answer 4

6.4÷12.5*8
=6.4÷125/10*8
=6.4*10/125*8
=6.4*2/25*8
=6.4*16/25
=6.4*0.64
=6.4*6.4*0.1
=（6.4*(6+0.4))*0.1
=(38.4+2.56)*0.1
=40.96*0.1
=4.096

Answer 5

这是小学五年级数学简便运算内容，一般都是用乘法交换律结合律和分配率解决，具体解答过程如下:
6.4÷12.5×8
=6.4×8÷12.5
=51.2÷12.5
=4.096
希望我的解答对你有所帮助！！
