Of course the answer given by the bot is nonsense
I will assume that those are supposed to be fractions.
Why not write them the normal way .... ?
Monday 2 1/8 hours or 17/8 hrs
Wednesday 1 1/2 hrs or 3/2 hrs
Friday 1 3/4 hours or 7/4 hrs
total = 17/8 + 3/2 + 7/4 hours
= (17 + 12 + 14)/8 hrs = 43/8 hours or 5 3/8 hrs or 5 hours and 22.5 minutes
