Calculating percentages can sometimes feel daunting, but breaking it down into simple steps makes it much easier. If you've ever wondered how to convert a fraction like ( \frac{18}{25} ) into a percent, you're in the right place! Let's dive into this straightforward guide that will not only show you how to do the calculation but also provide tips, tricks, and common pitfalls to avoid.

Understanding Percentages

Before we jump into the calculation, it’s essential to understand what a percentage is. A percentage is essentially a way of expressing a number as a fraction of 100. For example, 50% is the same as saying 50 out of 100. When converting a fraction to a percent, the goal is to express the fraction in this format.

Steps to Calculate ( \frac{18}{25} ) as a Percent

1. Start with the Fraction: You have ( \frac{18}{25} ).

2. Divide the Numerator by the Denominator: [ 18 \div 25 = 0.72 ]

3. Multiply by 100: To convert the decimal into a percent, multiply by 100. [ 0.72 \times 100 = 72 ]

4. Add the Percent Sign: Finally, don’t forget to add the % sign! [ \frac{18}{25} = 72% ]

This means ( \frac{18}{25} ) is equal to 72%. Simple, right? 😊
