Define fraction (1)

A fraction represents a part of a whole or a collection of objects. It is written as a ratio of two numbers, separated by a horizontal line.

The number on top is called the numerator. The number at the bottom is called the denominator.

Here are four types of fractions:

• Proper Fraction: A fraction where the numerator is smaller than the denominator. It represents a value less than one. Example: $\frac{3}{4}$
• Improper Fraction: A fraction where the numerator is greater than or equal to the denominator. It represents a value greater than or equal to one. Example: $\frac{7}{5}$
• Mixed Fraction (or Mixed Number): A number consisting of a whole number and a proper fraction. Example: $2\frac{1}{3}$
• Equivalent Fractions: Fractions that represent the same value, even though they have different numerators and denominators. Example: $\frac{1}{2} \text{ and } \frac{2}{4}$
