0.125.0.25.0.375.0.5是什么规律
0.125 0.25 0.375 0.5.第十个数是什么
0.5+0.25+0.125+0.0625+0.03125怎样速算
找规律填数：2,0.5,（ ）,0.03125. 1：0.25 2：0.125找规律填数：2,0.5,（ ）,0.03125. 1：0.25 2：0.125 3：0.35
0.25*（-0.125）*（-64）
规则是这样的：0.125=1 0.25=1 0.375=2 0.5=1 0.625=2 0.75=2 0.875=3此组数字实际是1/8进位,即0.125一进位,在0.125、0.25、0.5的时候等于1,0.375=0.125+0.25,因此等于2,0.625=0.5+0.125,也等于2.0.75=0.5+0.25,也等于2,0.875=0.
