Question About Calculation

[Anonymous]

Sample:

Phase	INPUT	OUTPUT	RESULT
PP	10	5	Division of Cleared with Input
PRO	20	10	Division of Cleared with Input
OT	30	15	Division of Cleared with Input
Overall			PP*PRO*OT

I have added the Measure to calculate Cleared with Input which is the division of Cleared being Numerator with Input being Denominator.

How do i multiply the Results of all three phases and get the FINAL RESULT in the Overall Row as mentioned above?
