gmat题目
Four extra-large sandwiches of exactly the same size were ordered for m students,where m > 4.Three of the sandwiches were evenly 均匀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?
答案是(4m-12)/(m(m-4))
先给你概括下这道题,
一共四个面包.其中三个平分给m个学生,另一个平分给(m-4)个学生.
Carol是从每个面包都吃一块,问她吃的是多少.
那么C吃的就应该是,3/m 和 1/(m-4) 这两部分(就是两个fraction),把这两个部分加起来,你看看是多少.
(满意就加分)
可以打电话问问海翔的陈文彬老师。
建议去海翔问问,老师都很不错的
