Row percent based on row total in a matrix

Hello,

I have been trying to do a seemingly easy calculation, but with no success...

Below is the output of a matrix that I get in Desktop. What I want to do is to get a matrix that contains % values based on the totals of each row (so, 3/19, 14/19, 2/19  .... 11/55, 21/55, and so on).

The values inside my matrix are frequencies, i.e. the number of cases where Rows=X and Columns=Y.

I attempted using SumX with AllExcept, etc but no luck. I cannot get my formula to keep the Totals (19, 55, 18) as constants so that my division can work.

Any help much appreciated!
