Converting Decimal Hour to HH:MM Format

Hi Syndicate_Admin 

Try this column

Column = 
VAR _hours = INT('Table'[TIMEDECHOURS])
VAR _minutes = ROUND(('Table'[TIMEDECHOURS]-_hours)*60,0)
RETURN
RIGHT("0"&_hours,2)&":"&_minutes

With above code, the column is of Text type. If the hours part is larger than or equal to 100 hours, it would return an incorrect value. You need to modify the hours part in that case. And I used ROUND function for minutes part. You could replace it with ROUNDUP or ROUNDDOWN if needed.
