In mathematics, a fraction is a way of writing a rational number as a quotient of two integers.
If we have to integers A and B, the quotient of A by B is a fraction, in this fraction A is called the numerator and
B the denominator.

Example of fraction: 4/8 (4 is the numerator of the fraction and 8 is its denominator).## What is an irreducible fraction?

A fraction is irreducible when we can't find an integer greater than 1 to simplify its numerator and denominator.

Example of irreducible fractions: 5/4; 1/3; 10/7; 8/5.
