1.25*6.17+0.125*18.3简便计算

1.25*6.17+0.125*18.3简便计算
1.25*6.17+0.125*18.3简便计算

1.25*6.17+0.125*18.3简便计算
1.25*6.17+0.125*18.3
=1.25*6.17+1.25*1.83
=1.25*(6.17+1.83)
=1.25*8
=10

0.125X(61.7+18.3)=10

= 1.25*6.17+1.25*1.83
=1.25*(6.17+1.83)
=1.25*8
=10

0.125X61.7+0.125X18.3=0.125X(61.7+18.3)=0.125X80=10

原式=0.125(61.7+18.3)=0.125*80=10
