Hi Jmac. Welcome to SpanishDict. Would you mind adding your language details to your profile please? - rac1, Aug 10, 2016

There is an automatic translator on the home page that usually gives three results for comparison. Try it! - jtaniel, Aug 10, 2016

I'm not too sure if it would translate this correctly. - rac1, Aug 11, 2016

Also, you can double-click on any word on the comments and you can find the general translation word-by-word. :) - Findy, Aug 11, 2016

Answer 1

The thing is, don't give the literal translation.

1. Es beneficioso ser fluido en dos idiomas. (Understandable but not idiomatic.)
2. Consider be fluent = hablar con fluidez (NOT ser fluido.)
3. Having said that, the idiomatic translation could be:
   Es beneficioso hablar con fluidez dos idiomas, or Es beneficioso hablar dos idiomas con fluidez.
