How many hours did Judy work on Monday,Tuesday,and Wednesday?
Monday=3hours and 15minutes
Tuesday=5hours and 30minutes
Wednesday=4hours and 45minutes
I got 1hour and 30minutes in all.. Is that correct?

No.
Think again. 
After I add all the numbers I get 12:90..
I don't get what I'm suppose to do next 
Yes, it's 12 hours and 90 minutes
60 minutes = 1 hour
So it's 13 hours and 30 minutes. 
So I was suppose to add 1 hour to 12hours and 90minutes?

Yes. You regroup (or borrow) 60 minutes from 90 minutes and add it to 12 hours.

Oh.
I get it now! Thanks 
Yay! :)
You're welcome.
