Definition: Fraction

A fraction represents a numerical value, which defines the parts of a whole.

It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator.

Equivalent fractions can be generated by multiplying the numerator and the denominator by the same number.

Definition: Simplification Fraction

A fraction expressed in its simplest or most reduced form is called a simplification fraction.

This process helps reduce the fraction to its simplest form.
