I want to know the answer to the following question:
How much of the world's population did the British Empire rule in 1922?
All the background I'm provided with is that "By 1922 the British Empire held sway over about 458 million people, one-fifth of the world's population at the time, and covered more than 13,000,000 sq mi (33,670,000 km2), almost a quarter of the Earth's total land area.". Is that enough to answer the question?
