Knowing how to convert fractions to percentages is a valuable skill in various aspects of life, from calculating discounts to understanding statistics. This article will guide you through the process, using the example of 12/15 as a percentage. We'll break it down into simple steps that anyone can follow.

Understanding Fractions and Percentages

Before diving into the conversion, let's refresh our understanding of fractions and percentages. A fraction represents a part of a whole, expressed as a ratio of two numbers (numerator/denominator). A percentage, on the other hand, represents a fraction of 100. The symbol "%" denotes a percentage.

How to Convert 12/15 to a Percentage

Here's a step-by-step guide to converting the fraction 12/15 to a percentage:

Step 1: Divide the Numerator by the Denominator

The first step is to divide the numerator (12) by the denominator (15). This gives you a decimal value.

12 ÷ 15 = 0.8

Step 2: Multiply the Decimal by 100

Once you have the decimal value (0.8), multiply it by 100 to convert it into a percentage.

0.8 x 100 = 80

Step 3: Add the Percentage Symbol

Finally, add the percentage symbol (%) to indicate that the result is a percentage.

Therefore, 80% is the percentage equivalent of the fraction 12/15.

Simplifying Fractions First (Optional but Helpful)

In some cases, simplifying the fraction before converting it to a percentage can make the calculation easier. For example, the fraction 12/15 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 3.

12 ÷ 3 = 4 15 ÷ 3 = 5

This simplifies the fraction to 4/5. Now, follow the steps above:

4 ÷ 5 = 0.8 0.8 x 100 = 80%

As you can see, the result is the same, regardless of whether you simplify the fraction beforehand. However, simplifying can make the division step simpler.

Other Examples of Fraction to Percentage Conversions

Let's look at a couple more examples to solidify your understanding:

Example 1: Converting 3/4 to a percentage:

3 ÷ 4 = 0.75 0.75 x 100 = 75%
Example 2: Converting 1/2 to a percentage:

1 ÷ 2 = 0.5 0.5 x 100 = 50%

Using a Calculator for Conversions

For more complex fractions, a calculator can be a useful tool. Most calculators have a percentage function that will directly convert a fraction to a percentage. Simply input the fraction as a division problem (numerator divided by denominator) and then multiply by 100.

Frequently Asked Questions (FAQs)

Q: What is the easiest way to convert fractions to percentages?

A: The easiest way is to divide the numerator by the denominator and then multiply the result by 100. Adding the "%" symbol completes the conversion.

Q: Why is it sometimes helpful to simplify a fraction before converting it to a percentage?
