percentage by categories of another variable

[launat]

Hello. How are they? I have problems with a DAX formula. I need to create a measure that calculates a % of values ​​but not on a total of cases but rather takes as 100% a single category of another variable. Step example:

DATE                    VALOR                  ANSWERED        OPINIÓN

MAY                         0.5                        rojo                       A

JUL                           0.4                        celeste                  A

MAY                          0.2                       negro                    B

JUL                           0.8                          rojo                     A

the measure should return the % of answered by color of all those who gave their opinion A. Then x date is filtered
