1.25x0.25 0.6

1.25一0.25X0.6的简算是1.25一0.25X0.6=1.25-0.15=1.1直接计算

等于0.6 简便的话,因为1.25=0.25*5,0.25*4=1所以就是:0.6*[0.25*(5-1)]=0.6*(0.25*4)=0.6*1=0.6

小学题目吧.方程两边同时除以0.75.则x-0.25=0.8再方程两边同时加0.25.则x=1.05

解: 1.25x0.25x0.5x64 =1.25*8*0.25*4*0.5*2 =10*1*1 =10 亲,请您采纳,您的采纳是我的动力,谢谢.

把64分成4x4x4所以原式变成1.25x0.25x0.5x4x4x4=1.25x4x0.25x4x0.5x4=5x1x2=10

1.25x0.25x4x0.4=1.25x0.4x0.25x4=(1.25x0.4)x(0.25x4)=0.5x1=0.5 答题不易,望采纳!!

1.25x0.25x0.32x36.1=(1.25*0.8)*(0.25*0.4)*36.1=1*0.1*36.1=3.61

1.25x0.25x0.05x64=1.25x0.25x0.05x8*8=1.25x8x0.25x(0.05x8)=10x0.25x0.4=2.5x0.4=1

3.76x0.25-0.6=3.76÷4-0.6=0.94-0.6=0.34
