What Percent of 5 is 2? Unlocking the World of Percentages

Percentages are a powerful tool for understanding relationships between numbers. They allow us to express a part of a whole as a fraction out of 100. In this article, we'll explore the question "What percent of 5 is 2?" and learn how to solve such problems.

Understanding the Concept

The question "What percent of 5 is 2?" is essentially asking: "If 5 is our whole, what fraction of that whole is represented by 2, expressed as a percentage?"

The Solution

Here's how to find the solution:

1. Set up a proportion: We can represent the problem as a proportion:

   2 / 5 = x / 100 
   

   • 2 represents the part we're interested in.
   • 5 represents the whole.
   • x represents the unknown percentage.
   • 100 represents the whole expressed as a percentage.

2. Solve for x: To solve for x, we can cross-multiply:

   2 * 100 = 5 * x
   200 = 5x
   

3. Isolate x: Divide both sides by 5:

   x = 200 / 5
   x = 40
   

Therefore, 2 is 40% of 5.

Practical Applications

Understanding percentages is crucial for many real-life situations:

• Sales and Discounts: Knowing what percent of a price is discounted helps us determine the final price.
• Financial Calculations: Interest rates are often expressed as percentages, allowing us to calculate interest earned or owed.
• Data Analysis: Percentages are widely used to represent and analyze data, allowing us to compare and interpret information more effectively.

Key Takeaways

• Percentages represent a part of a whole as a fraction out of 100.
• We can use proportions to solve for unknown percentages.
• Understanding percentages is crucial for various practical applications.
