1250*0.037+0.125*160+12.5*2.7怎样简便计算
1250*0.037+0.125*160+12.5*2.7
=1250*0.037+1250*0.016+1250*0.027
=1250*(0.037+0.016+0.027)
=1250*0.08
=100
1250*0.037+0.125*160+12.5*2.7
=12.5*3.7+12.5*1.6+12.5*2.7
=12.5*(3.7+1.6*2.7)
=12.5*8
=100
1250*0.037+0.125*160+12.5*2.7
=125*0.37+125*0.16+125*0.27
=125*(0.37+0.16+0.27)
=125*0.8
=100
1250*0.037+0.125*160+12.5*2.7=1.25*37+1.25*16+1.25*27=1.25*(37+16+27)=1.25*80=5/4*80=100
