爱loli非瑞骂娶,你好:
12.5×88.8
=12.5×80+12.5×8+12.5×0.8
=1000+100+10
=1110
12.5×88.8
=12.5×8×11.1
=100×11.1
=1110
1 12.5*88.8
=12.5*(8*11.1)
=12.5*8*11.1
=100*11.1
=1110
2 12.5*88.8
=(5*2.5)*(22.2*4)
=(2.5*4)*(5*22.2)
=10*111
=1110
12.5×88.8
12.5×10×8.88
=125×8×1.11=1000×1.11
=1110
12.5*80+12.5*8+12.5*0.8
88.8分成11.1和8然后8剩12.5=100再升11.1
