I want to know the answer to the following question:
How much did the Ukrainians make up in population as a percentage in East Prussia?
All the background I'm provided with is that "In 1950 the Olsztyn Voivodeship counted 689,000 inhabitants, 22.6% of them coming from areas annexed by the Soviet Union, 10% Ukrainians, and 18.5% of them pre-war inhabitants.". Is that enough to answer the question?
Answer: yes
