125÷(12.5 ÷0.08 )脱式计算点算法

125÷(12.5 ÷0.08 ) =125÷12.5/0.08 =125x0.08/12.5 =10x0.08 =0.8 谢谢,请采纳

=12.5÷0.4=31

60÷0!?是吗!?什么叫脱试计算

(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.

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

(1)17.5÷12.5×1.4,=1.4×1.4,=1.96;(2)1.58×99+1.58,=1.58×(99+1),=1.58×100,=158;(3)4.38÷0.125÷8,=4.38÷(0.125×8),=4.38÷1,=4.38;(4)6.4×4.5+3.6×4.5,=(6.4+3.6)×4.5,=10×4.5,=45.

=5/12÷(-3/5×6/5) =5/12÷(-18/25) =-5/12×25/18 =-125/216

8.8×12.5 =1.1×(8×12.5) =1.1×100 =110 25.3×12减33.95÷0.35 =303.6-97 =206.6

(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
