1. What is a Fraction Addition Calculator?

Definition: This calculator performs addition of two fractions using the standard mathematical method of finding a common denominator.

Purpose: It helps students, teachers, and professionals quickly and accurately add fractions without manual calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \frac{a}{b} \) — First fraction
• \( \frac{c}{d} \) — Second fraction
• The result is automatically simplified to lowest terms

Explanation: The calculator finds a common denominator by multiplying the denominators, then adds the numerators accordingly.

3. Importance of Fraction Addition

Details: Adding fractions is fundamental in mathematics, used in measurements, ratios, probability, and many real-world applications.

4. Using the Calculator

Tips: Enter numerators and denominators for both fractions. Denominators must be positive integers. The calculator shows the raw result, simplified form, and decimal equivalent.

5. Frequently Asked Questions (FAQ)

Q1: Why do we need a common denominator?
A: Fractions can only be directly added when they have the same denominator, as they represent parts of the same whole.

Q2: What if denominators are already the same?
A: The calculator still works - it will simply add the numerators while keeping the denominator.

Q3: How does the simplification work?
A: The calculator uses the greatest common divisor (GCD) to reduce the fraction to lowest terms.

Q4: Can I add mixed numbers?
A: Convert mixed numbers to improper fractions first (e.g., 1½ = 3/2).

Q5: What about negative fractions?
A: Negative numerators are allowed (e.g., -1/2 + 1/4 = -1/4).
