问题 Quantity A: 4/5-4/7
Quantity B: 4/7-2/5

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

解析两个数都加上(2/5+4/7)，Quantity A变为6/5，Quantity B变为8/7，两者继续都减1，Quantity A变为1/5，Quantity B变为1/7，当然选择A。
