53000除以125的巧算

- -
=53*(1000÷125)

53000÷125
=53×1000÷125
=(50+3)×(1000÷125)
=(50+3)×8
=50×8+3×8
=400+24
=424

53000/125
=53x1000/125
=53x8
=(50+3)x8
=50x8+3x8
=400+24
=424

50000/(25*5)+3000/(25*5)
50000/5=10000
10000/25=400
3000/5=600
600/5=120
120/5=24
400+24=424

53000/125
=(53000*8)/(125*8)
=424000/1000
=424

125*8=1000
所以53000除以125=53*8*125/125=53*8=424

53000/125
=53000*8/125*8
=53*8*1000/1000
=53*8
=424

53000÷125
=53000÷(1000÷8)
=53000÷1000×8
=53×8
=424

原式=(53*125*8)/125
=53*8
=424
保证对

125*8=1000
所以53000除以125=53*8=424
