Yeah stuff like that really ain’t it. It works in a few use cases, but is objectively wrong and detracts from understanding the topic properly. That’s why I teach percentages as the fractions they are. By the time you learn percentages, you already know multiplying fractions is commutative, so the trick still works, and you also understand why.

What about pi%?
That’s pi/100 still. Didn’t say it was a rational number, just that it was a fraction. Though I don’t see a context where it’d make sense.
