问题
Quantity A: 1/100+1/99+1/98+1/97+1/96
Quantity B: 1/20
选项
A、Quantity A is greater.
B、Quantity B is greater.
C、The two quantities are equal.
D、The relationship cannot be determined from the information given.
答案
A
解析
把Quantity A各项进行通分是比较笨的做法。分析两边的数,发现1/20=5×1/100,也就是可以认为1/20是5个1/100相加,这样和Quantity A中的各项一一比较。因为1/99,1/98,1/97,1/96每一项都大于1/100,所以Quantity A大于Quantity B,A为正确答案。
