0.79乘0.46加7.9乘0.24加11.4乘0.079怎么简算,求过程

Answer 1

你好，经过观察可以发现，每个乘法式子里都包含乘数0.79的倍数，经过变换，可以把0.79提取出来，方法如下：
0.79*0.46+7.9*0.24+11.4*0.079
=0.79*0.46+0.79*2.4+1.14*0.79
=0.79*（0.46+2.4+1.14）
=0.79*4
=3.16

Answer 2

0.79×0.46+7.9×0.24+11.4×0.079
= 0.79×0.46+0.79×2.4+1.14×0.79
= 0.79×（0.46+2.4+1.14）
= 0.79×4
= 3.16

Answer 3

0.79×(0.46+2.4+1.14)=0.79×4=3.16
