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 :)

No but seriously, why do you think it necessarily needs to be different? There are calculators that use actual fraction notation and all that
It's not that it needs to be different, it's that it is. The fact that there are calculators with fractional notation is completely irrelevant.
