Question

What is the difference between Usted & Ustedes?

and Tú as well??

How can I say when, "You are from Peru, therefore you are peruana."

Answer 1

Well, usted and ustedes are both the formal forms of 'you;' usted is singular 'you,' and ustedes is plural 'you.' In English we use the same word for both singular and plural. Tú is the informal form of 'you.' In your question, which form you would use would depend upon whether you are speaking to someone you know well, or not.
