Understanding how to convert percentages to fractions is a fundamental skill in math. This guide will show you how to easily convert 15 percent into its fractional equivalent, and we'll explore some related concepts along the way. Knowing this skill helps with everything from baking (following recipes) to calculating discounts in a shop.

Understanding Percentages and Fractions

Before diving into the conversion, let's quickly review the basics:

Percentage: A percentage represents a fraction of 100. The symbol "%" signifies "out of 100." So, 15% means 15 out of 100.
Fraction: A fraction shows a part of a whole, expressed as a ratio of two numbers – the numerator (top number) and the denominator (bottom number). For example, 1/2 represents one part out of two equal parts.

Converting 15% to a Fraction: Step-by-Step

Converting 15% to a fraction is straightforward:

Write the percentage as a fraction: 15% can be written as 15/100. This directly represents the meaning of 15 out of 100.
Simplify the fraction: Both the numerator (15) and the denominator (100) are divisible by 5. Dividing both by 5, we get 3/20.

Therefore, 15% as a fraction is 3/20. This is the simplest form of the fraction.

Practical Applications: Using 15% as a Fraction

Understanding this conversion allows you to solve various problems:

Calculating Discounts: A store offers a 15% discount. To figure out the discount on a $100 item, you can multiply $100 by 3/20. This equals $15, representing the discount amount.
Recipe Adjustments: Recipes sometimes require adjustments. If a recipe calls for 15% more of an ingredient, you would use 3/20 to calculate the necessary increase.

Other Percentage to Fraction Conversions

The same method applies to other percentages. Here are a few examples:

25%: 25/100 simplifies to 1/4.
50%: 50/100 simplifies to 1/2.
75%: 75/100 simplifies to 3/4.

FAQs about Converting Percentages to Fractions

Q: How do I convert a percentage greater than 100% to a fraction?

A: Follow the same steps. For example, 125% becomes 125/100, which simplifies to 5/4 or 1 1/4 (a mixed number).

Q: What if the fraction cannot be simplified?

A: If the numerator and denominator share no common factors other than 1, the fraction is already in its simplest form.

Conclusion: Mastering Percentage to Fraction Conversions

Converting 15 percent to a fraction (3/20) is a simple yet valuable mathematical skill. By understanding this process, you can confidently tackle various problems involving percentages and fractions in everyday situations. Remember the key steps: write the percentage as a fraction over 100, and then simplify if possible.
