title: Convert decimal (2.75) to time (2:45)
body: <p>If I have a double like 2.75, is there a way in .Net to format it as '2:45'</p>
  
  <p>If it is for example, 2.75555555555, it should round it to the nearest minute.
  I would not mind coding this myself, but I am wondering if .Net can. I checked ToString but did not find anything.</p>
  
  <p>Thanks</p>
