Working with Mixed Fractions

A mixed fraction consists of a whole number and a proper fraction (e.g., 2 3/4). It represents the sum of the whole number and the fraction part.

Converting Between Mixed and Improper Fractions

Mixed to Improper: (Whole × Denominator + Numerator) / Denominator

Example: 2 3/4 = (2 × 4 + 3) / 4 = 11/4

Improper to Mixed: Whole = Numerator ÷ Denominator (integer division), Remainder/Denominator

Example: 11/4 = 2 3/4 (11 ÷ 4 = 2 with remainder 3)

Arithmetic Operations with Fractions

Addition: a/b + c/d = (a×d + b×c) / (b×d)

Subtraction: a/b - c/d = (a×d - b×c) / (b×d)

Multiplication: a/b × c/d = (a×c) / (b×d)

Division: a/b ÷ c/d = (a×d) / (b×c)

Simplifying Fractions

To simplify a fraction, divide both the numerator and denominator by their greatest common divisor (GCD).

Example: 8/12 = (8÷4) / (12÷4) = 2/3

The greatest common divisor of 8 and 12 is 4, so we divide both by 4 to get the simplified fraction.

Disclaimer: This calculator provides accurate fraction arithmetic for educational purposes. For critical applications requiring high precision, verify calculations with specialized tools or consult with a mathematics professional.

Mixed to Improper: (Whole × Denominator + Numerator) / Denominator

Improper to Mixed: Whole = Numerator ÷ Denominator (integer division), Remainder/Denominator

Add/Subtract Fractions: a/b ± c/d = (a×d ± b×c) / (b×d)

Multiply Fractions: a/b × c/d = (a×c) / (b×d)

Divide Fractions: a/b ÷ c/d = (a×d) / (b×c)
