65*0.37-6.5*2.7= 求简便算法?
65*0.37-6.5*2.7= 求简便算法?
65*0.37-6.5*2.7= 求简便算法?
65*0.37-6.5*2.7
=6.5×3.7-6.5×2.7
=6.5×(3.7-2.7)
=6.5×1
=6.5
65*0.37-6.5*2.7
=6.5×10×0.37-6.5×2.7
=6.5×3.7-6.5×2.7
=6.5×(3.7-2.7)
=6.5×1
=6.5
65*0.37-6.5*2.7
=6.5×（3.7-2.7）
=6.5×1
=6.5
原式= 6.5*3.7-6.5*2.7=6.5*(3.7-2.7)=6.5*1=6.5
6.5*（3.7-2.7）=6.5*1=6.5
65*0.37-6.5*2.7
=65×0.37-65×0.27
=65×（0.37-0.27）
=65×0.1
=6.5
6.5*3.7-6.5*2.7=6.5*（3.7+2.7)=6.5*6.4=41.6
