66.6×22.2+33.3×33.4怎么简便运算？

Answer 1

66.6*22.2+33.3*33.4=33.3*44.4+33.3*33.4=33.3*（44.4+33.4）=33.3*77.8=2590.74。以上就是简便运算。

Answer 2

66.6×22.2+33.3×33.4
=33.3×2×22.2+33.3×33.4
=33.3×（22.2×2+33.4）
=33.3×77.8
=（30+3+0.3）×77.8
=30×77.8+3×77.8+0.3×77.8
=2334+233.4+23.34
=2567.4+23.34
=2590.74

Answer 3

66.6*22.2+33.3*33.4=33.3*44.4+33.3*33.4=33.3*（44.4+33.4）=33.3*77.8=2590.74。
以上就是简便运算。

Answer 4

你可以把66点6×22点二，换成33点3×44点四，然后这个档次就写成了！33点3×44点4，加上33点3×33点四，等于33.3乘以括号44点4+33点四，括号，等于33点3×77点八

Answer 5

66.6x22.2＋33.3x33.4
＝33.3x2x22.2＋33.3×33.4
＝33.3x44.4＋33.3x33.4
＝33.3x〈44.4＋33.4）
＝33.3x77.8
＝2590.74
