如何简算0.37*2400*0.25+4*8.75+2.825*40
如何简算0.37*2400*0.25+4*8.75+2.825*40
如何简算0.37*2400*0.25+4*8.75+2.825*40
0.37*2400*0.25+4*8.75+2.825*40
=37*6*4*0.25+4*27/4 +28.25*4
=37*6+27+72+1
=37*6+(27+72+1)
=222+100
=322
0.37*2400*0.25+4*8.75+2.825*40
=(0.37x100)x6x(4x0.25)+4x(8.5+0.25)+(2.8+0.025)x10x4
=37x6+34+1+28x4+0.25x4
=(40-3)x6+35+112+1
=240-18+148
=240+140
=380
4*8.75+2.825*40=4*(8.75+28.25)=4*37
0.37*2400*0.25=37*6*4*0.25=37*6
yuanshi=37*6+4*37=10*37=370
先提出来一个4然后列式
4*(0.37*600*0.25+8.75+2.825*10)
=4*(0.37*600*0.25+37)
=4*(37*6*0.25+37)
=4*37*(1.5+1)
=4*37*2.5
=370
=37*24*0.25+4*8.75+28.25*4
=37*6*(4*0.25)+4*(8.75+28.25)
=37*(6+4)
