Possible to divide each column value of a table by each column value of another table ?

[Anonymous]

Hi,

I have a table A with these columns: site_name, monthly_productibility. I also have a table B with these columns: site_name,monthly_production. I want to divide the column monthly_production (table B) by the column monthly_productibility (table A).

When I try the DIVIDE function (fast measure or DAX function):

DIVIDE(
    SUM('TABLE_B'[monthly_production]),
    COUNTA('TABLE_A'[monthly_productibility]))

The results are just so wrong, I tried different formulas but still doesn't work and I want to merge the tables only if I am obligated to do so (I am more into a generic approach).

Thank you by advance for your answer,

@Anonymous , You can create a common site table analyze against that, Why one is a sum and another is count

Try like

DIVIDE(
SUM('TABLE_B'[monthly_production]),
sum('TABLE_A'[monthly_productibility]))

Hi, 

Well this doesn't work, but I finally found out the answer.

DIVIDE(
    SUM('TABLE_B'[monthly_production]),
    AVERAGE('TABLE_A'[monthly_productibility]))
