Understanding fractions and converting them to percentages can be a fundamental skill in various mathematical and real-world applications. One common fraction that often requires conversion to a percentage is 5/4. In this article, we will explore how to convert 5/4 to a percentage, discuss the importance of such conversions, and provide practical examples.
Understanding Fractions and Percentages
Before diving into the conversion process, it's essential to understand what fractions and percentages represent. A fraction is a way to express a part of a whole, consisting of a numerator (the top number) and a denominator (the bottom number). In the case of 5/4, the numerator is 5, and the denominator is 4.
On the other hand, a percentage is a way to express a value as a fraction of 100. Percentages are often used to represent proportions, rates, or increases/decreases in various contexts.
Converting 5/4 to a Percentage
To convert the fraction 5/4 to a percentage, you can follow these steps:
- Divide the numerator (5) by the denominator (4): 5 ÷ 4 = 1.25
- Multiply the result by 100 to convert it to a percentage: 1.25 × 100 = 125%
Therefore, 5/4 as a percentage is 125%.
