3 hours 30 minutes = 3.5 hours
2.5
It is 1.5 hours
First you divide by 60 to find the hours. In this case, you do 1800/60 and get 30. There is no decimal part or remainder and so there will be no minutes. Therefore, in 1,800 minutes, there is exactly 30 hours.

Take just the decimal, and multiply it by 60. So if you have 3.5 hours, you do 0.5 x 60 to get 30 minutes. If you have 6.48 hours, you do 0.48 x 60 to get 28.8 minutes, for which you can do the same thing with the decimal to get seconds (0.8 x 60 = 48 seconds)
