How to do operations between detail row with total rows of matricial table

[Andrea_Fuentes]

I have a inconvenent to obtein one calculated column doing two operations, one of sum and other of division as I show in this image:

Resulted must be agregated to one table of visualization type matriz.

In the before picture the operation is for each row:

Row 1) 41 * 18 / 253 = 3 (value is round) 

Row 2) 100 * 18 / 253 = 7

Row 3) 103 * 18 / 253 = 7

Row 4) 9 * 18 / 253 = 1

Note: Column CxIndex and #Pac Fallecidos are obteined with a messure for each one.

CxIndex =

VAR Valor =

CALCULATE(DISTINCTCOUNT('hce CirugiaCardioPediatrica'[IdDimCirugiaSts]), 

FILTER('hce CirugiaCardioPediatrica', 'hce CirugiaCardioPediatrica'[CirugiaIndex] = 1)) --> Marca que indica que es Index (1)

RETURN

IF(ISBLANK(Valor), 0, Valor) --> Validate null values

Pac Fallecidos = -- Pacientes fallecidos agrupados por grupo etario

CALCULATE(DISTINCTCOUNT('hce CirugiaCardioPediatrica'[IdCliente]),

FILTER('hce CirugiaCardioPediatrica','hce CirugiaCardioPediatrica'[Estado Egreso] = "Muerto"),

FILTER('hce CirugiaCardioPediatrica', 'hce CirugiaCardioPediatrica'[CirugiaIndex] = 1) --> Cx Index (única por atención)

)

Hi @Andrea_Fuentes 

Place this measure in the table visual you show above

Measure =
VAR aux1_ = CALCULATE ( [CxIndex], ALL ( Table1[Grupo_Etario] ) )
VAR aux2_ = CALCULATE ( [Pac Fallecidos], ALL ( Table1[Grupo_Etario] ) )
RETURN
    SUMX (
        DISTINCT ( Table1[Grupo_Etario] ),
        ROUND ( DIVIDE ( [CxIndex] * aux2_, aux1_ ), 0 )
    )
