What is a Fraction Calculator?
A fraction calculator is an online tool that performs arithmetic operations on fractions. Instead of solving problems manually, you just enter two fractions, select the operation (addition, subtraction, multiplication, or division), and instantly get the result in simplified form.
This tool is particularly useful for:
- Students learning basic arithmetic with fractions.
- Teachers preparing exercises or solutions.
- Professionals who deal with measurements, recipes, or data.
- Anyone looking to save time when working with fractions.
Key Features of the Fraction Calculator
✔️ Easy Input – Enter fractions in the form a/b (e.g., 1/2, 3/4).
✔️ Four Operations Supported – Add, subtract, multiply, or divide fractions.
✔️ Instant Results – Get the answer simplified to its lowest terms.
✔️ Error Handling – Alerts if the fraction is invalid (e.g., denominator zero).
✔️ Reset Option – Quickly clear inputs and start a new calculation.
How to Use the Fraction Calculator
Using the calculator is simple and straightforward:
- Enter the first fraction in the box labeled First Fraction (a/b).
- Example:
1/2
- Example:
- Choose an operation from the dropdown menu:
+for addition−for subtraction×for multiplication÷for division
- Enter the second fraction in the box labeled Second Fraction (c/d).
- Example:
3/4
- Example:
- Click the “Calculate” button.
- The result will instantly appear in simplified form.

Example Calculations
Here are some real examples of what you can do with the calculator:
Example 1: Adding Fractions
Input: 1/2 + 3/4
Steps:
- Common denominator = 4
- (1×2 + 3×2)/4 = 5/4
Simplified Result: 5/4 or 1 1/4
Example 2: Subtracting Fractions
Input: 5/6 − 1/3
Steps:
- Common denominator = 6
- (5 − 2)/6 = 3/6
Simplified Result: 1/2
Example 3: Multiplying Fractions
Input: 2/5 × 3/7
Steps:
- Numerator: 2 × 3 = 6
- Denominator: 5 × 7 = 35
Simplified Result: 6/35
Example 4: Dividing Fractions
Input: 4/9 ÷ 2/3
Steps:
- Flip the second fraction → 3/2
- Multiply: (4 × 3) / (9 × 2) = 12/18
- Simplify: 2/3
