Table of Contents :
To find out what number 80 is 20% of, we need to set up a simple equation. Understanding percentages is crucial in everyday life, and knowing how to manipulate them can save you from confusion in both personal finances and academic scenarios.
Understanding Percentages
Percentages represent a fraction of 100. So, when we say 20%, we mean 20 out of every 100, or 20/100. To find what number a certain percentage represents, you can use the following formula:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]
In our case:
- Part = 80
- Percentage = 20%
- Whole = the number we want to find (let's denote this as ( x ))
Setting Up the Equation
Using the percentage formula, we can rearrange it to solve for the whole:
[ 20 = \left( \frac{80}{x} \right) \times 100 ]
By simplifying, we can move forward:
- First, divide both sides by 100:
[ 0.2 = \frac{80}{x} ]
- Now, multiply both sides by ( x ):
[ 0.2x = 80 ]
- Finally, divide both sides by 0.2:
[ x = \frac{80}{0.2} = 400 ]
Conclusion
So, 80 is 20% of 400. This example illustrates how to calculate percentages effectively, and understanding these concepts can significantly assist in making sense of various numerical relationships in both academic and real-world situations.
