Formal:
* Oui, vous le faites. (This is a literal translation, but it sounds very formal and might not be natural in everyday conversation.)
Informal:
* Oui, tu le fais. (This is the most common and natural way to say it in informal contexts.)
* Si, tu le fais. (This is another informal option, meaning "yes, you do it.")
* Bah oui, tu le fais. (This is a more casual and playful way to say it, meaning "well yeah, you do it.")
Examples:
* Do you eat apples? - Yes, you do.
* Tu manges des pommes ? - Oui, tu le fais.
* Do you like coffee? - Yes, you do.
* Tu aimes le café ? - Si, tu le fais.
* Do you play the piano? - Yes, you do.
* Tu joues du piano ? - Bah oui, tu le fais.
It's important to consider the context and the person you're speaking to when choosing the most appropriate translation.
