Four extra-large sandwiches of exactly the same size were ordered for m students, where m > 4. Three of the sandwiches were evenly divided among the students. Since 4 students did not want any of the fourth sandwich, it was evenly divided among the remaining students. If Carol ate one piece from each of the four sandwiches, the amount of sandwich that she ate would be what fraction of a whole extra-large sandwich?

一共有4个超级大三明治给m个同学吃（m>4),其中3个三明治被平均的分给了同学。由于4个学生不想吃第四个三明治了，所以分给了剩下（m-4）个学生。如果C每个三明治都吃了一片，那她吃的这个些占一个三明治的几分之几？
c第一次吃3个三明治时候吃到的是3/m 第二次吃第四个三明治吃到1/（m-4）===>总共吃到3/m+1/（m-4）和一个三明治的比就是3/m+1/（m-4）：1 就得出E这个答案了。

看半天才看明白每个饼是单独分给同学们的。。。一开始还以为前面三个饼一起分给m个同学。。。。gmac我劝你不要太玩文字游戏

一起分也没毛病。。。3/m和1/m+1/m+1/m是一样的。。。
