From the beginning of last year, Price per share increased K percent. Earning per share increased M percent. Question: ask the ratio in percentage for price per share to earning per share in increase. In term of K, M.
[确认](100*(K-M)/(100+M)) 。

[em27][em27][em27]

分子[p(1+k%)]/[e(1+m%)]-(p/e)
分母p/e
解得(k%-m%)/(1+m%)
不好意思，格式看起来不爽，落到纸面，就会清楚得多。[em08][em08][em09]
