I have no idea what 1/1/2 or 3/1/2 means.
Ever heard of measurements?
Don’t be such a smart ass. The way you wrote it is unconventional, if not wrong.
What you meant, I presume, is 1-1/2 and 3-1/2.I didn’t recognize what you wrote as such until just now, either.
But also, it’s a rank order, so why use half-measures anyway? That’s also unconventional, adding confusion.
Why should I conform to your conventions? That and people do use halves in lists, ala Lion King, Lion King 1/1/2 and Lion King 2. Usually, you see point number but I decided to do the unexpected.
