Division between Different Matrixes

[F_Rehman2007]

Hi,

I am working on two existing  matrixes - Matrix 1 and Matrix 2 - both of which come from the very same SQL Server Table source.

Matrix 1 - Total Population.

Matrix 2 - The subset within the Total Population which fulfils a specified criteria (which I am working with).

Matrix 3 is what I am trying to create i.e Division of each Matrix 2 value over their corresponding value in Matrix 1. The Percentage values in Matrix 3 below are only HARD-CODED and is what I am trying to calculate  .

Please advise on the best way to create Matrix 3.
