11.1×666+778×33.3简便计算

11.1×666+778×33.3简便计算
11.1×666+778×33.3
=22.2×333+77.8×333
=[22.2+77.8]×333
=100×333
=33300


原式=11.1*666+778*33.3
=11.1*666+778*3*11.1
=11.1(222*3+778*3)
=33.3(222+778)
=33.3*1000
=33300
祝您学习进步!!!

解:
11.1×666+778×33.3
=11.1×666+777×33.3+33.3
=11.1×333×2+777×33.3+33.3
=33.3×(222+777+1)
=33.3×1000
=33300
祝你开心

=11.1*666+778*11.1*3
=11.1*(666+778*3)
