There are 75 more women than men enrolled in Linden College.If there are n men enrolled,then,in terms of n,what percent of those enrolled are men?B.n/ (2n+75) %E.(100n)/ (2n+75) %我看来看去都觉得是B,那个100是哪里冒出来的?是不是我题目理解错了

问题描述:

There are 75 more women than men enrolled in Linden College.If there are n men enrolled,then,in terms of n,what percent of those enrolled are men?
B.n/ (2n+75) %
E.(100n)/ (2n+75) %
我看来看去都觉得是B,那个100是哪里冒出来的?是不是我题目理解错了

E

很显然是E啊,n/(2n+75)就已经是结果了,但是要把它变成百分数就要乘以100%,那当然就是E了,B相当于是结果除以100

我刚开始看也被迷惑了
后来发现选项的后面有个%好
如果选择B的话,直接就是答案,而不需要%号,否则会比答案的比例少100倍
但如果在B的基础上乘以100则跟%号可以相抵消
就是这样.答案应该是E

因为加了百分号,所以式子前边乘以100,比如0.5表示成百分数,就是0.5*100%了
做题要注意细心哦
