To convert a fraction into a percentage, understanding the formula and method behind it is essential. In this article, we will explore how to calculate 15 out of 25 as a percentage, along with practical examples and a step-by-step guide.
What is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. It's denoted using the symbol "%". Understanding percentages is crucial in various aspects of daily life, from calculating discounts while shopping to understanding scores in exams.
The Formula for Percentage Calculation
To find the percentage of a number, you can use the following formula:
[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 ]
In our case:
- Part = 15
- Whole = 25
Step-by-Step Calculation
Now, let's apply the formula to our specific example:
-
Identify the Part and Whole:
- Part = 15
- Whole = 25
-
Divide the Part by the Whole: [ \frac{15}{25} = 0.6 ]
-
Multiply by 100: [ 0.6 \times 100 = 60 ]
So, 15 out of 25 is 60%.
Understanding the Result
This means that 15 represents 60% of the total 25. It's essential to grasp this concept as it applies to various situations, such as grading systems, statistics, and data analysis.
