During a certain season, a football team won one-thid of the first half games, what percent of the second half games were not won by the team?
(1)The team won one-fourth of the total games during the season
(2)The team played a total of 18 games during the season.

sorry 忘了說 答案是A , why?

設前半贏的場數X, 前半共打了3X場
後半也打了 3X場, 後半贏的場數為Y

(X+Y)/(3X+3X) = 1/4

剩下的算看看吧~~
