0.888×9.2+0.222×3.2的简便计算
0.888×9.2+0.222×3.2的简便计算

0.888×9.2+0.222×3.2的简便计算
0.888x9.2+0.222x3.2=0.888x9.2+0.222x4x0.8=0.888x9.2+0.888x0.8=0.888x(9.2+0.8)=0.888x10=88.8

0.888*9.2+0.222*4*0.8
=0.888*(9.2+0.8)
=8.88

0.888×9.2+0.222×3.2
=0.888×9.2+0.222×4×0.8
=0.888×9.2+0.888x0.8
=0.888×(9.2+0.8)
=0.888x10
=8.88

0.222x4x9.2+0.222x4x0.8=0.888x(9.2+0.8)=0.888x10=8.888
