数学问题(小数化分数)

Answer 1

首先
如果系小数后两个位
就把所有点数乘100分之100(小数后三位的
就乘1000/1000
如此类推)
因为100分之100=1
所以8.95乘了100分之100
也不会影响其本身之数值
但又能把他的小数化为分数 如第一个8.95
把它乘100分之100 8.95 X 100/100 =895/100 =8又95/100 =8又19/20 0.075 =0.075 X1000/1000 =75/1000 =3/40 5.005 =5.005X1000/1000 =5005/1000 =5又5/1000 =5又1/200 24.15 =24.15 X 100/100 =2415/100 =24又 15/100 =24又3/20 11.34 =11.34 X100/100 =1134/100 =11又34/100 =11又17/50 31.954 =31.954 X 1000/1000 =31954/1000 =31又 954/1000 =31又 477/500 4.125 =4.125 X 1000/1000 =4125/1000 =4又 125/1000 =4又 1/8 10.05 =10.05 X 100/100 =1005/100 =10又 5/100 =10又 1/20 2.724 =2.724 X 1000/1000 =2724/1000 =2又 724/1000 =2又 181/250 3.25 =3.25 X 100/100 =325/100 =3又25/100 =3又1/4 32.18 =32.18 X 100/100 =3218/100 =32又18/100 =32又9/50 17.6 =17.6 X 10/10 =176/10 =17又 6/10 =17又 3/5 14.625 =14.625 X 1000 =14625/1000 =14又625/1000 =14又 5/8 9.1625 =9.1625 X 10000/10000 =91625/10000 =9又1625/10000 =9又 13/80 1.888 =1.888 X 1000/1000 =1888/1000 =1又888/1000 =1又111/125 0.08 =0.08 X 100/100 =8/100 =2/25 520.5 =520.5 X 10/10 =5205/10 =520又 5/10 =520又 1/2 27.04 =27.04 X 100/100 =2704/100 =27又4/100 =27又 1/25 0.546 =0.546 X1000/1000 =546/1000 =273/500 0.33 =0.33 X 100*100 =33/100 14.0208 =14.0208 X 10000/10000 =140208/10000 =14又208/10000 =14又 13/625 7.258 =7.258 X 1000/1000 =7258/1000 =7又 258/1000 =7又 129/500 9.92 =9.92 X 100/100 =992/100 =9又92/100 =9又 23/25 60.02 =60.02 X 100/100 =6002/100 =60又 2/100 =60又1/50
