问题如下：
Suppose that the quote between currency A and currency B is 1.2000 and that currency B is the base currency. How many units of currency A should be exchanged for 100 units of currency B?
解释：
A is the quote currency. The quote indicates that 120 units of A should be exchanged for 100 units of B.
老师，怎么根据题干判断报价形式啊，李老师不是说FRM 默认的报价形式是A/B吗？
这道题为啥不是A/B=1.2，而是1.2A=B？
