I just did an exercise from a textbook on Passe compose. The exercise requires you write the correct form of the words in brackets.
Q-.Combien de femmes avez-vous (Voir)?
My answer was: Combien de femmes avez-vous vu?
But the answer given by the textbook was: Combien de femmes avez-vous vues?
Which answer is correct and why because I know passe compose using avoir does not agree with gender. Help with explanation if I am wrong
