hours between two dates and time

Very new to excel.
I'm simply trying to get the amount of hours minutes between two dates and time.

e.g hours between
06/09/2007 10:35:00 and 07/09/2007 15:30:00

I can get the amount of days and the hours(only if it doesn't go longer than a day)

There are a lot of formula out there that are to complicated for me and I don't know how to dissemble.
Any help much appreciated.
