Everyday Applications
From calculating discounts at the store to understanding nutritional labels, percentages play a role in daily life.
Understanding the Formula
The core formula involves dividing the part (130,000 in this case) by the whole (1,000,000) and multiplying by 100.
Step-by-Step Calculation
Divide 130,000 by 1,000,000, resulting in 0.13. Then, multiply 0.13 by 100 to arrive at the percentage, which is 13%.
Practical Examples
Consider a scenario where a company’s total revenue is 1,000,000 and a specific product contributes 130,000. This product accounts for 13% of the total revenue.
