A certain basketball team that has played 2/3 of its game has a record of 17 wins and 3 lossed.What is the greatest number of the remaining games that the team can lose and still win at least 3/4 of all of its games?我自己算出答案是5,但是答案是4,我也不知道为什么,如果方便的话把答题过程也一起贴上吧!感激不尽!
答
很容易算出赛季共30场（(17+3)/(2/3)）.
问的是最多还能输几场（设为x）,于是得：
(30-3-x)/30 >= 3/4
解出x
