Pet peeve warning! Danger! Danger Will Robinson!

Just for the record here, I dislike proper fractions.
It's not the concept, it's the form of the number. Something like "1 1/3" is likely to be misconstrued either as 11/3 or 1 times 1/3. The only saving grace to them is when it is typed in some sort of font such as , but this also can be taken to be .
I think overall it's much better just to leave it as 4/3.

You have to wait for a problem to spring up. And yes that does take time, but that's the way it is. I think the Americans have started with school and university again, so there will be plenty of problems again soon. There are times when it gets very busy on the forum. Just be patient.
By the way do you have a degree in mathematics?
