Understanding the relationship between two numbers is a fundamental mathematical skill. Calculating percentages allows for comparisons and provides context for data interpretation. This article explores the process of determining what percentage one number represents of another, specifically using the example of 130,000 and 1,000,000. The calculation method and the underlying formula are explained, providing a clear and concise guide for practical application.
Key Concepts
Proportionality is central to percentage calculations. A percentage represents a fraction of a whole, expressed as a value out of 100.
The Formula
The basic formula for calculating percentage is: (Part/Whole) * 100 = Percentage.
Practical Application
This formula can be applied to various scenarios, from financial analysis to scientific research.
Step-by-Step Calculation
Divide the smaller number (130,000) by the larger number (1,000,000). Multiply the result by 100.
Example Calculation
(130,000 / 1,000,000) * 100 = 13%
Interpreting the Result
130,000 is 13% of 1,000,000.
Importance in Data Analysis
Percentage calculations facilitate data comparisons and trend identification.
Real-World Applications
Examples include calculating discounts, investment returns, and population growth.
Benefits of Understanding Percentages
