Going to
free cloud link
clicking on "Create A New Notebook", entering
CountryData["UnitedStates","LanguagesFractions"]
in the page, clicking on Evaluate on the bar above the page and then clicking Evaluate Cells does appear to provide the complete list of languages and the fractions.
Repeating that with
CountryData["PapuaNewGuinea","LanguagesFractions"]
results in "The Wolfram Engine has been terminated because the evaluation time limit was reached".
Unfortunately, the error message does not indicate what particular product enforced that constraint or how to overcome it. Perhaps someone who has a subscription to WolframAlphaPro could sign in before trying this and determine whether the time constraint that will be removed with a Pro subscription, or even a trial.
Signing into the cloud for free use before trying the query did not change the result.
Perhaps someone with more knowledge or access can track down what is really required to overcome that time limit for this specific query so that the person can get the information.
