变式计算怎么算66.6X2.2+33.3X15.6？

Answer 1

66.6×2.2+33.3×15.6
=33.3×2×2.2+33.3×15.6
=33.3×4.4+33.3×15.6
=33.3×(4.4+15.6)
=33.3×20
=666

Answer 2

可以把66.6换成33.3x2，然后在计算就可以了。66.2x2.2+33.3x15.6=33.3x.2.2+33.3x15.6=33.3x(4.4+15.6)=33.3x20=666。

Answer 3

计算过程如下
66.6X2.2+33.3X15.6
=66.6X2.2+33.3X2X7.8
=66..6X2.2+66.6X7.8
=66.6X（2.2+7.8）
=66.6X10
=666
望采纳

Answer 4

66.6️️️️x2.2+33.3x15.6
=(33.3x2)x2.2+33.3x15.6
=33.3x4.4+33.3x15.6
=33.3x(4.4+15.6)
=33.3x20
=666

Answer 5

66.6×2.2+33.3×15.6
=66.6×2.2+(33.3×2)×(15.6÷2)
=66.6×2.2+66.6×7.8
=66.6×(2.2+7.8)
=66.6×10
=666
