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.
64×0.125×0.5×0.25=（8×4×2）×0.125×0.5×0.25=（8×0.125）×（2×0.5）×（4×0.25）=1×1×1=1
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
2×0.25×0.125＝2×1/4×1/8＝1/16再问：32*00.25*0.125再答：32×1/4×1/8＝1
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
0.25×32×0.125=0.25×4×8×0.125=（0.25×4）×（8×0.125）=1×1=1
0.25-x=0.125×0.625x=1/4-5/64x=11/64不明白欢迎来求助!多谢了!
5/13=0.3846153846153846很有意思的数字
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
0.25*（-0.125）*（-64）=0.25×4×0.125×8×2=1×1×2=2
/>0.125：0.25=（0.125×1000）：（0.25×1000）=125：250=1：2
0.25*0.25/(0.25+0.25)
0.125×0.25×32，=（0.125×8）×（0.25×4），=1×1，=1．
3.2×0.25×0.125=0.4×0.25×8×0.125=0.1×1=0.1
0.5+0.25+0.125+.+0.0078125=(1-0.5)+(0.5-0.25)+(0.25-0.125)+……+(0.015625-0.0078125)=1-0.0078125=0.992
