Real-World Examples
Example 1: Market Research
If a market research study finds that 20% of a city’s population prefers a certain product, and the city has a population of 100,000, then the number of people who prefer the product is:
100,000 * 0.20 = 20,000
Example 2: Epidemiology
If a disease affects 15% of a country’s population, and the country has a population of 50 million, then the number of people affected by the disease is:
50,000,000 * 0.15 = 7,500,000
Example 3: Sports
If a team has a win rate of 60%, and they have played 100 games, then the number of games they have won is:
100 * 0.60 = 60
