Calc working hours based on GT% of another column?

[singleton2787]

I have the table so far below that I want to calc the working hours spent by the GT% of the workitems

I have a calendar table already...

So if the % of workitems is let's say 10% and there are 120 work hours in that month, I want to display that 12 hours were spent
