Fraction symbols
A fraction is a mathematical expression representing the division of one quantity by another. It is composed of two parts: a numerator (the top number) and a denominator (the bottom number), separated by a horizontal line. Fractions are used to express parts of a whole, ratios, and proportions in a concise manner.
Components of a Fraction
In a fraction a/b:
- Numerator (a): The number above the fraction line, representing the quantity being considered.
- Denominator (b): The number below the fraction line, representing the total number of equal parts into which the whole is divided.
Types of Fractions
Fractions can be classified into different types based on their characteristics:
- Proper Fraction: The numerator is less than the denominator (0 < a < b).
- Improper Fraction: The numerator is equal to or greater than the denominator (a ≥ b).
- Mixed Number: A combination of a whole number and a proper fraction (e.g., 2 1/3).
Representation in HTML

Operations with Fractions
Fractions can be involved in various mathematical operations, including addition, subtraction, multiplication, and division. The rules for these operations depend on the specific operation being performed.
Applications
Fractions are used in a wide range of real-world scenarios, such as cooking recipes, measurement conversions, and financial calculations. They provide a flexible and intuitive way to express parts of a whole or relationships between quantities.
Example
Consider the fraction 2/3. Here, 2 is the numerator (representing two parts), and 3 is the denominator (indicating the whole is divided into three equal parts).
Fractions are a fundamental concept in mathematics, offering a concise and precise way to represent relationships between quantities. They are essential in various mathematical applications and are foundational for understanding more advanced mathematical concepts.
