把160拆成4*40,那么25*160*125=(25*4)*(40*125)=100*5000=500000.
25乘160乘125=(25X4)X5X(8X125)=100X5X1000=500000
5400除150除4=5400除(150X4)=5400除600=9
40X55=40X5X11=200X11=2200
25×160×125
=25×4×40×125
=100×(40×125)
=100×5000
=500000
25×160×125=(25×4)×5×(8×125)=100×5×1000=500000
5400除150除4 =5400÷(150×4)=5400÷600=9
40乘55=40×5×11=200×11=2200
25×160×125
=(25×4)×(40×125)
=100×5000
=50000
---------------------------------------
5400÷150÷4
=5400÷(150×4)
=5400÷600
=9
----------------------------------------
40×55
=40×50+40×5
=2000+200
=2200
-----------------------------------------
