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 :)
Yes of course, we always used fractions so there was no ambiguity. Last time I saw the division symbol must have been in primary school!
You would've done dividing by fractions in high school, which requires both. Fractions and division aren't the same thing.
