1.08x0.8÷0.27 脱式计算 可以用简便方法

见图

原式 =(1.08÷0.27)x0.8 =4x0.8 =3.2

1.08x0.8÷0.27 =0.864÷0.27 =3.2

0.4×125×25×0.8 =(0.4×25)×(125×0.8) =10×100=1000 1.25×(8+10) =1.25×8+1.25×10 =10+12.5=22.5 9123-(123+8.8) =9123-123-8.8 =9000-8.8 =8991.2 1.24×8.3+8.3×1.76 =8.3×(1.24+1.76) =8.3×3=24.9 9999×1001 =9999×(1000+1) =9999×10...

=4.8-3*0.6+4 =4.8-1.8+4 =3+4=7
