8 hours and 12 minutes = 8 + (12/60) = 8 1/5
5 hours and 49 minutes = 5 + (49/60) = 5 49/60
8 1/5 - 5 49/60
(41/5) - (349/60)
Multiply everything by 60
(492/60) - (349/60) = (143/60) = 2 hours and 23 minutes

8 hours and 12 minutes can actually be written as 7 hours and 72 minutes (because 1 hour = 60 minutes.
8 hours and 12 minutes minus 5 hours and 49 minutes
= 7 hours and 72 minutes minus 5 hours and 49 minutes
= (7-5) hours and (72-49) minutes
= 2 hours and 23 minutes

Split them up into only minutes.
8 hours and 12 minutes = 492 minutes
5 hours and 49 minutes = 349 minutes
Now subtract: 492 - 349 = 143 minutes
Now break up 143 minutes into hours and minutes
143 min = 2 hours and 23 minutes
2 hours and 23 minutes is your answer

First, "borrow" from the hours...
8 hrs 12 mins = 7 hrs 72 mins
7h 72m - 5h 49m = 2 hours and 23 minutes

Aha...a question in time...

8 Hrs 12 Mins
5 Hrs 49 mins (Hmm-m, the minutes are to big on the bottom)
Rewrite it as:
7 Hrs 72 Mins
5 Hrs 49 Mins (now subtract as normal)
- - - - - - - - - - - - - - - - - - -
Answer: 2 Hrs 23 Mins
