What Is This Tool?
The Fraction Calculator works with two fractions and the operation you choose — add, subtract, multiply, or divide. You enter each numerator and denominator, pick an operation, and click Calculate to get the exact answer reduced to lowest terms. The result appears as a mixed number, as a decimal (with repeating digits shown in parentheses), and as a visual ring chart for each fraction. You can also download the result as a PDF.
How to Use This Tool?
- Enter the numerator and denominator of the first fraction.
- Choose an operation: +, −, ×, or ÷.
- Enter the numerator and denominator of the second fraction, then click Calculate.
- Review the result and download it as a PDF if needed.
Key Features
- Adds, subtracts, multiplies, or divides two fractions.
- Gives an exact answer reduced to lowest terms.
- Shows the result as a mixed number and as a decimal.
- Displays the repeating part of a decimal in parentheses, like 0.8(3).
- Includes a visual chart of each fraction and a PDF download.
Examples
- 1/2 + 1/3 equals 5/6, or 0.8(3).
- 3/4 − 1/4 equals 1/2.
- 2/3 × 3/4 equals 1/2.
- 1/2 ÷ 1/4 equals 2.
Common Use Cases
- Combining fractional measurements in cooking or DIY projects.
- Scaling recipes or quantities up or down with fractions.
- Checking fraction arithmetic homework.
- Converting a fraction result into a decimal for quick comparison.
- Teaching or learning the four operations with fractions.
Tips & Best Practices
- Use a positive denominator and put any negative sign on the numerator.
- Pick the operation before reading the result, since it changes the answer.
- Read parentheses in the decimal as the digits that repeat forever.
- Remember the answer is always reduced to lowest terms.
- Download the PDF to save or share the full result and chart.
Limitations
- Works with exactly two fractions at a time.
- Numerators must be whole numbers and denominators positive whole numbers.
- Dividing by a fraction with a zero numerator is not allowed.
- Handles fractions only, not mixed-number or decimal input.
Frequently Asked Questions
- Which operations does it support?
- It adds, subtracts, multiplies, and divides two fractions.
- How is the answer shown?
- As a reduced fraction or mixed number, plus a decimal with any repeating digits in parentheses.
- How does dividing fractions work here?
- Dividing by a fraction multiplies by its reciprocal; for example, 1/2 ÷ 1/4 equals 2.
- Can I save the result?
- Yes. You can download the result, including the chart, as a PDF.
Key Terminology
- Fraction
- A number written as a numerator over a denominator, such as 1/2.
- Mixed number
- A whole number combined with a proper fraction, such as 1 1/3.
- Reciprocal
- A fraction flipped upside down, used when dividing by a fraction.
- Repeating decimal
- A decimal with a digit block that repeats forever, shown in parentheses like 0.8(3).
- Lowest terms
- A fraction reduced so the numerator and denominator share no common factor.
