0.25x0.125x0.8x0.4简便运算

0.25x0.125x0.8x0.4=(0.25*0.4)*(0.125*0.8)=0.1*0.1=0.01

(0.4+0.8)*0.25*0.125=0.4*0.25*0.125+0.8*0.25*0.125=0.1*0.125+0.1*0.25=0.1*(0.125+0.25)=0.1*0.375=0.0375

0.125x0.32x0.25=0.125x0.4x0.8x0.25=(0.125x0.8)x(0.25x0.4)=0.1x0.1=0.01 ,你好,本题已解答,如果满意 请点右下角“采纳答案”.

(0.4+0.8)0.250.125=0.4x0.25x0.125+0.8x0.25x0.125=0.1x0.125+0.1x0.25=0.1x(0.125+0.25)=0.1x0.375=0.0375

0.25*0.4=0.10.8*0.125=0.10.1*0.1=0.01

原式=0.25x0.125x0.8x0.4=(0.25x0.4)x(0.125x0.8)=0.1x0.1=0.01供参考.

(0.25*0.125)*0.8=0.25*(0.125*0.8)=0.25*0.1=0.025

0.125X0.32X0.25简变运算=0.125x0.8x0.4x0.25=(0.125x0.8)x(0.4x0.25)=0.1x0.1=0.01

0.25x(8+0.4)x1.25=0.25*(8x1.25+0.4*1.25)=0.25*(10+0.5)=0.25*10+0.25*0.5=2.5+0.125=2.625

解:依题意得算式,0.25*0.5÷0.25*0.8=0.25÷0.25*(0.5*0.8)=1*0.4=0.4即0.25*0.5÷0.25*0.8=0.4
