解:9.4×0.12+0.6×0.3


=9.4×0.2×0.6+0.6×0.3


=0.6×(9.4×0.2+0.3)


=0.6×(1.88+0.3)


=0.6×2.18


=1.308

9.4*0.12+0.6*0.3
=(10-0.6)*0.12+0.6*0.3
=1.2-0.6*0.12+0.6*0.3
=1.2+0.6*(0.3-0.12)
=1.2+0.6*0.18
=1.2+0.108
=1.308

10×0.12-0.6×0.12+0.6×0.3
=1.2+0.6×0.18
=1.308

9.4x0.12+0.6x0,12+0.6x0.2-0.6x0.02
(9.4+0.6)x0.12+0.12-0.012
1.2+0,12-0.012
1.308

9.4*0.12+0.6*0.3=0.6(9.4*0.2+0.3)=0.6(1.88+0.3)=0.6*2.58
