根据0.37×18=3.7×1.8算出1.25×6.17+0.125×18.3怎么简便计算

根据0.37×18=3.7×1.8算出1.25×6.17+0.125×18.3怎么简便计算
根据0.37×18=3.7×1.8算出1.25×6.17+0.125×18.3怎么简便计算

根据0.37×18=3.7×1.8算出1.25×6.17+0.125×18.3怎么简便计算
1.25x6.17+0.125x18.3
=0.125x61.7+0.125x18.3
=0.125x(61.7+18.3)
=0.125x80
=10.

原式=1.25×6.17+1.25×1.83
=1.25x(6.17+1.83)
=1.25x8
=10
