Final answer:
Approximately 61.36% of European countries are members of the European Union, with the EU currently comprising 27 member states out of 44 countries in Europe.
Step-by-step explanation:
If there are 44 countries in Europe, about what percent belong to the European Union (EU)? As of the latest information, the EU consists of 27 member states. To find the percentage of European countries belonging to the EU, we can perform a simple calculation:
((Number of EU Member States) / (Total Number of European Countries)) x 100 = Percent of EU Member States
((27) / (44)) x 100 ≈ 61.36%
Therefore, approximately 61.36% of the countries in Europe are members of the European Union.
