Hi @fp92, I was in your same exact situation about this during my L1 days.
All your statements are correct. Let me attempt to clarify:
In the real world (NOT CFA curriculum), EUR/USD of 1.2 means 1 EUR = USD 1.2
However, in CFA curriculum, EUR/USD = 1.2 is read as EUR 1.2 per USD 1. Just remember that CFA convention is opposite from ‘rest of the world’.
For the purposes of the CFA curriculum, you should also be familiar with the convention of EUR:USD = 1.2, which means USD 1.2 = EUR 1, i.e. equals USD/EUR = 1.2.
Statement 3 above is important from an exam perspective. It’s important to note that the use of colon (:) is directionally opposite to using a slash (/), i.e. EUR:USD = USD/EUR in CFAI curriculum. In this case, USD is the numerator, EUR is the denominator.
