0.75*24+0.75/0.25的简便算法.0.75*24+0.75/0.25的简便算法.0.75*24+0.75/0.25的简便算法.=0.75*4*6+0.75/0.25=3*6+3=210.7

0.75*24+0.75/0.25的简便算法.
0.75*24+0.75/0.25的简便算法.

0.75*24+0.75/0.25的简便算法.
=0.75*4*6+0.75/0.25=3*6+3=21

0.75*24+0.75/0.25
=0.75*24+0.75*4
=0.75*(24+4)
=0.75*28
=0.25*3*4*7
=3*7*(0.25*4)
=21

0.75*24+0.75/0.25=0.75【24+1/(1/4)】=0.75(24+4)=0.75*4*7=3*7=21
