How Percent to Fraction Conversion Works

Converting a percentage to a fraction is straightforward: place the percentage value over 100 to create a fraction, then simplify it by dividing both the numerator and denominator by their Greatest Common Divisor (GCD). For example, 75% becomes 75/100, and since GCD(75, 100) = 25, the simplified fraction is 3/4.

For decimal percentages like 12.5%, first multiply both the numerator and denominator by a power of 10 to remove the decimal. So 12.5% becomes 125/1000, and after simplification with GCD(125, 1000) = 125, you get 1/8. This method works for any percentage, including repeating decimals. You can also convert percentages to decimals with our Percent to Decimal converter, or work with fractions directly using the Fraction Calculator.

Frequently Asked Questions

How do I convert a percentage to a fraction?

Write the percentage as a number over 100 (e.g., 75% = 75/100), then simplify the fraction by dividing both parts by their greatest common divisor. 75/100 simplifies to 3/4.

How do I handle decimal percentages like 33.33%?

First multiply both numerator and denominator by a power of 10 to eliminate the decimal. For 33.33%, multiply by 100 to get 3333/10000, then simplify. For exact thirds, 33.33% approximates to 1/3.

What is the GCD and why is it used?

The GCD (Greatest Common Divisor) is the largest number that divides evenly into two numbers. It is used to simplify fractions to their lowest terms. For example, GCD(50, 100) = 50, so 50/100 simplifies to 1/2.

Can any percentage be expressed as a fraction?

Yes, every percentage can be expressed as a fraction. Some result in simple fractions (25% = 1/4), while others may have larger denominators. Repeating decimals like 33.33% are approximations of exact fractions like 1/3.

What is 25% as a fraction?

25% as a fraction is 1/4. Write 25 over 100 (25/100), then simplify by dividing both by GCD(25, 100) = 25, giving 1/4.

What is 50% as a fraction?

50% as a fraction is 1/2. Write 50/100, then divide both by GCD(50, 100) = 50 to get 1/2.

What is 75% as a fraction?

75% as a fraction is 3/4. Write 75/100, then divide both by GCD(75, 100) = 25 to get 3/4.

How do I convert a mixed number percentage to a fraction?

For mixed numbers like 12.5%, write the value over 100 first: 12.5/100. Multiply both top and bottom by 10 to clear the decimal: 125/1000. Then simplify with GCD(125, 1000) = 125 to get 1/8.
