30/2
half of 30 is 15, so 15 added to 15 would equal 30. if you go from there and add one number and subtract one number from each 15 (14 plus 16, 13 plus 17, ect...all the way to 0 plus 30) these numbers will also total to 30.
it is 2hr and 15 mins
1/6 + 7/10 = 5/30 + 21/30 = 26/30 = 13/15
No. It is close, but not exact. 1/3 + 1/5 = 5/15 + 3/15 = 8/15 = 16/30 1/2 = 15/30 thus 16/30 != 15/30

8:30 plus 45 minutes equals 9:15. To add the two times together, you can convert 8:30 to 8:00 and add the 45 minutes to get 8:45. Then, adding another 30 minutes gives you a total of 9:15.
15+15=30. If you did not know this answer than go back to kindergarten you stupid, fat so.

5 hour 30 minutes
it is 2hr and 15 mins
1/6 + 7/10 = 5/30 + 21/30 = 26/30 = 13/15
No. It is close, but not exact. 1/3 + 1/5 = 5/15 + 3/15 = 8/15 = 16/30 1/2 = 15/30 thus 16/30 != 15/30
-30 plus 60 = 30
30 + 25 + 15 + 25 = 95
