125÷(12.5 ÷0.08 )脱式计算点算法

12.5×8÷12.5×8 =(12.5÷12.5)x(8x8) =1x64 =64

3.25除以12.5除以0.8的脱式计算 3.25除以12.5除以0.8 =3.25÷(12.5*0.8) =3.25÷10 =0.325

34.5÷0.23÷12.5 =150÷12.5 =12

(1)0.8×(12.5+1.25)=0.8×12.5+0.8×1.25=10+1=11;(2)7.75×[20÷(3.24-3.04)=7.75×(20÷0.2)=7.75×100=775;(3)4.05÷0.81+2.4=5+2.4=7.4.

(1)(124-85)×12÷26,=39×12÷26,=468÷26,=18;(2)(75+360)÷(20-5),=435÷15,=29;(3)19.92+14.4-9.92,=19.92-9.92+14.4,=10+14.4,=24.4;(4)85.7-(15.3-4.8),=85.7-10.5,=75.2;(5)9.5+4.85-6.13,=14.35-6.13,=8.22...

240÷5÷12简便算法脱式计算 240÷5÷12 =240÷(5*12) =240÷60 =4

12.8×0.5x4.8÷1.5 =6.4x4.8÷1.5 =30.72÷1.5 =20.48

4.8÷1/5+12×20%脱式计算 =4.8x5+12x0.2 =24+2.4 =26.4
