Percent to Fraction Calculator

Convert a percentage to an exact simplified fraction, with steps showing how the result is calculated.

Enter percentage

Enter a whole number or a finite decimal, using a decimal point (12.5). Repeating-decimal and mixed-number notation are not supported.

Exact fraction

3/4

The exact fraction uses every decimal digit you enter. A simpler fraction for a rounded percentage is an approximation.

75% = 75/100

GCD(75, 100) = 25

= 3/4

What is 58.33% as a fraction?

58.33% is exactly 5833/10000. Write 58.33 over 100, then multiply both the numerator and denominator by 100 to remove the decimal point. Since 5833 and 10000 have no common factor greater than 1, the fraction is already in simplest form.

Why do some tables show 7/12?

7/12 equals 58.333…%, which rounds to 58.33%. So 7/12 is a useful approximation for a rounded percentage, while 5833/10000 is the exact fraction for the number 58.33%.

Common Conversions

Exact fractions use the percentage as written. Values marked ≈ are common approximations, not equal values. A dash means no separate approximation is shown.

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 applies to finite decimal percentages. Repeating decimals need a different method and cannot be entered using repeating notation here. 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%?

33.33% is exactly 3333/10000. One third equals 33.333…%, so 33.33% is a rounded approximation of one third, not exactly 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?

Whole-number and finite decimal percentages can be written as exact fractions. Repeating decimals can also represent rational numbers, but this calculator does not accept repeating-decimal notation. Non-repeating infinite decimals are irrational, so they cannot be written as a ratio of integers.

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 decimal percentage to a fraction?

For a finite decimal such as 12.5%, write 12.5/100. Multiply both parts by 10 to get 125/1000, then divide both by 125 to get 1/8. Mixed-number notation such as 12 1/2 is not accepted as input; enter 12.5 instead.
