Answer 1

我的计算方法如下：
0.8888*0.6+0.2222*7.6
=0.1111*8*0.6+0.1111*2*7.6
=0.1111*（4.8+15.2）
=0.1111*20
=2.222
各步骤应该口算可以得到答案，不知道能否帮到你。

Answer 2

0.8888*0.6+0.2222*7.6
=0.2222×4×0.6+0.2222×7.6
=0.2222×2.4+0.2222×7.6
=0.2222×（2.4+7.6）
=0.2222×10
=2.222

Answer 3

0.8888×0.6+0.2222×7.6
= 0.2222×4×0.6+0.2222×7.6
= 0.2222×2.4+0.2222×7.6
= 0.2222×（2.4+7.6）
= 0.2222×10
= 2.222

Answer 4

0.8888x0.6+0.2222x7.6
=0.2222x(4x0.6+7.6)
=0.2222x(2.4+7.6)
=0.2222x10
=2.222
