Help me with writing this in brazilian portuguese, please?

Question

can you tell me how to write this in brazilian portuguese, for someone in brazil to understand:

this is what i want to translate:

' im not sure i know you. how did you get my number? '

Answer 1

im nao certo eu conheço-o. como você começou meu número? '

Answer 2

If your going to Brazil dont wear anything fancy( waches, earings, bracelets,etc.) and dont show your money!!!

"Eu nao sei que te coneso.Commo que voce pegou meu numero de telephone?"

Answer 3

"Eu nao tenho certeza se eu conheco voce. Como voce conseguiu meu numero?"

By the way, watch people you meet online, I saw many Americans meeting people over the internet, when they get there they get kidnapped, or raped and/or murdered. It was all over the news last time I went to Brazil.

Answer 4

Eu nao tenho certeza se te conheco.  Como voce conseguiu o meu numero?

Answer 5

Bfiori and RNJ are absolutely correct. Ignore the first two translations as they are really bad.

I also agree with RNJ on being careful when in Brazil. Foreigners are targetted the moment they step off the plane!
