thanks a lot, today see one new vewion of 分饼. confuse me again.
5. 分饼那题,昨天的jj不太清楚,4个饼,有3个饼分给所有的m(m>4)人,最后一个饼,有4个人不想要,于是分给剩下的人,其中小明分到4个饼的每一片,问小明分到的数量占个饼的多少,表达式表示,不难。
【参考版本】4个cake,学生m个(不是具体数值)m>4。把3个cake平均分成若干pieces分给学生。剩下的一个cake没人愿意吃掉整个,就把它等分给剩下的学生。有一个人Carol吃了every piece of the 4 cake,他一共吃了多少piece? 答案是包含m的表达式
当时我没明白“剩下的学生”是指谁,没吃着前3块的?

sorry I don't get it, is the answer 3 ?
3/m + 1/(m-4) = 3 ?
anyone please explain a bit for me? thanks!作者: bluebird 时间: 2002-11-13 10:21

definitely should be 3/5, sorry for carelessness again. That's probably the reason why I only get 49 in math yesterday. thank you for the correction.作者: librayang 时间: 2002-11-17 09:13
