I wrote a (very long) blog post about those viral math problems and am looking for feedback, especially from people who are not convinced that the problem is ambiguous.

It's about a 30min read so thank you in advance if you really take the time to read it, but I think it's worth it if you joined such discussions in the past, but I'm probably biased because I wrote it :)

But stating the division as a fraction completely changes my mind now about how this calculation works

But division and fraction aren't the same thing - the former separates terms, the latter is a single term.

(140-age)(kg) / 72(SCr) vs (140-age) X kg ➗72 X SCr

The different answers for these two isn't because of / vs ➗, but because in the second one you have added extra multiplications in, thus breaking up some of the terms, and SCr has consequently been flipped from being in the denominator to being in the numerator. i.e. AK/72Scr vs. AK/72xSCr.
