7.5×0.48+4.8×0.25怎么简便计算
7.5×0.48+4.8×0.25怎么简便计算

7.5×0.48+4.8×0.25怎么简便计算
7.5×0.48+4.8×0.25
=7.5×0.48+0.48×2.5
=0.48x(7.5+2.5)
=0.48x10
=4.8

7.5×0.48+4.8×0.25
=7.5*0.48+0.48*2.5
=0.48*(7.5+2.5)
=0.48*10
=4.8

7.5×0.48+4.8×0.25
=0.75×4.8+4.8×0.25
=(0.75+0.25)×4.8
=1×4.8
=4.8

0.48×(7.5+10×0.25)=0.48×(7.5+2.5)=0.48×10=4.8
