Ratio to Fraction Calculator
Enter a ratio (A : B) to convert it into fraction equivalents in simplest form.
Ratio to Fraction Calculator – Convert Ratios to Simplest Fractions
A Ratio to Fraction Calculator is a simple yet powerful tool that allows you to convert any ratio into fraction form. Whether you are working with part-to-part ratios or part-to-whole ratios, this calculator reduces the fractions to their simplest form, making it easy to understand and apply in real-world situations.
Ratios are commonly used in mathematics, science, finance, and daily life, while fractions are a standard way to represent parts of a whole. Converting ratios to fractions helps in calculations, comparisons, and problem-solving.
What Is a Ratio to Fraction Calculator?
A ratio to fraction calculator converts the terms of a ratio into fractions and simplifies them. You can input:
- Part-to-part ratios – comparing one part to another (e.g., 3:4)
- Part-to-whole ratios – comparing a part to the total (e.g., 3 out of 7)
The calculator automatically reduces the fractions to their simplest form using the greatest common factor (GCF).
How to Use the Ratio to Fraction Calculator
Using the calculator is straightforward:
- Enter the first term of the ratio (A)
- Enter the second term of the ratio (B)
- Choose whether it is part-to-part or part-to-whole
- Click Calculate
- View the fraction equivalents and simplified results
The calculator provides a clear, step-by-step solution, so you can see how the fractions are derived from the ratio.
Ratio to Fraction Formulas
- Part-to-part ratio (A:B):
Fraction for A = A / (A + B) (if converting to part-to-whole)
Fraction for B = B / (A + B) - Part-to-whole ratio:
Fraction = Part ÷ Whole
After calculating, the fractions are simplified by dividing the numerator and denominator by their greatest common factor (GCF).
Example 1: Part-to-Part Ratio
Given: Ratio = 3:5
Step 1: Write as fractions of each term to the total:
- Fraction of 3 = 3 / (3 + 5) = 3 / 8
- Fraction of 5 = 5 / (3 + 5) = 5 / 8
Result: 3:5 → 3/8 : 5/8
Example 2: Part-to-Whole Ratio
Given: 2 parts out of 7
Step 1: Fraction = Part ÷ Whole = 2 ÷ 7
Result: Fraction = 2/7 (already simplified)
