0.25*40.4+0.125*10.8=0.25*（40+.04）+0.125*（10+0.8）=0.25*40+0.25*0.4+0.125*10+0.125*0.8=10+0.1+1.25+0.
0.125×0.32-0.25×0.16=0.125×0.32-0.125×2×0.16=0.125×0.32-0.125×(2×0.16)=0.125×0.32-0.125×0.32=0
72*0.125*0.25*0.4=(72*1/8)*(1/4*0.4)=9*0.1=0.9
400*(1-0.25)-32*0.125=400*0.25*3-4*8*0.125=300-4=296
4,把小数化分数就可以了再问：过程再答：再问：这样够简便吗再问：我要最简便的再答：够简便了
0.125*32=0.125*8*4=1*4=4
0.125*0.25*0.5*64=0.125*8*0.25*4*0.5*2=1*1*1=1再问：8从哪来再答：64=8*4*2
1/8*1/4*1/2*2/5=1/160
32x0.25x0.125=4x8x0.25x0.125=4x0.25x8x0.125=(4x0.25)x(8x0.125)=1x1=1这里的技巧是您看到0.25和0.125,您就可以想到4x0.25
0.25×32×0.125=0.25×4×8×0.125=（0.25×4）×（8×0.125）=1×1=1
15*888+32*0.125*0.25=15*8*111+8*4*0.125*0.25=120*111+1=100*111+20*111+1=11100+2220+1=13321
0.25x32x0.125=(0.25x4)x(0.125x8)=1x1=1
77.5×0.125＋0.25×1.25＝77.5×0.125＋2.5×0.125＝0.125×（77.5＋2.5）＝0.125×80＝0.125×8×10＝1×10＝10
原式=0.125x8x4x2.5=1x10=10
0.125*32*25=0.125*8*4*25=（0.125*8）*（25*4）=1*100=100求采纳
=4*0.25*8*0.125*25.68=25.68
0.125×0.25×32，=（0.125×8）×（0.25×4），=1×1，=1．
（0.125-0.25÷4×0.25）÷0.5=（1/8-1/4x1/4×1/4）x2=(1/8-1/64)x2=1/8x2-1/64x2=1/4-1/32=(8-1)/32=7/3232分之7
