How do you say who is 40 years old in French?

To ask the question "who is 40 years old" you can say, Qui a quarante ans? When talking about age you use "avoir" which means "to have" so really you are saying "who has 40 years" to English speakers like us it's very strange. Hope that helps. Here are some other age statements and questions: How old are you? Combien des ans avez-vous? I am (age here). J'ai _______ He/She is (age) Il/Elle a _____ Is he/she eleven? a-t*-il/elle onze ans? *The "t" is only there to make the sentence flow better in speach. Hope that helps! :) Elizabeth
