How many hours left do I have to use? Math calc

I have 27 days to use a year. But this year I have to use half the amount which is 13.5 days

I work 7.5 hours for 1 day of work.

I have used 13 days now, but how many hours/minutes is the .5?

Do you mean 0.5 of the hour or of the day? They both have 0.5 on the end. Either way, 0.5 = 1/2 so 0/5 hour = 1/2 hour = 30 minutes. If you mean 0.5 of your day, that is 1/2 of 7.5 hours, and that is 3.75 hours (just divide 7.50 by 2) that is 3 hours and 0.75 hour, which is 3/4 hour = 45 minutes, so that would be 3 h 45 m

If 7.5 hours= 1 work day then7.5/2=3.75 hours= 3 hours and 45 minutes
=.5 work days

If you work 7,5 hours on one day then you work 3,75 hours on half a day.

So I'd say the answer is 3 hours and 45 minutes

There are 24 hours in a day; half that is 0.5 * 12 = exactly 12 hours.
