Mon père a trente-neuf ans is a French equivalent of the English phrases "My father is 39" and "My father's 39." The statement translates literally as "My father has 39 years" in English. The pronunciation will be "mo peh-ra trawnt-nuh-vaw" in French.
"Thirty-nine" in English is trentanove in Italian.
Sources seem to indicate that about 39% of the French population speaks English.
The vast majority. The French, like many other Europeans, are forced to learn English in school, so very few at this point would not be able to speak, or at least understand some English.
"39, rue Ganneron" IS French!
