I think the context is quite commutative.

Also, the last line is what made me think to search if this com exists, and I think it stands on its own

The context is a post that said percentages are reversible, which is false, and exact vocabulary is super important in maths. Reversible has a precise meaning, and so does commutative, and mixing words in maths and science isn't conducive to learning. The first commenter is right, it should be commutative, and I expanded on that, saying that that's the case because percentages are fractions. I think the rest is in the screenshot, lmk if I'm still being unclear
