Introduction to Rational Numbers
The notion of dividing is present in our daily lives, for example, dividing a pizza is a simple process that reminds us of the notion of fraction.
The first word we see in fraction is half or half.
$$\dfrac{1}{2}$$
History of the representation of rational numbers
The great mathematicians took a long time to understand the representation of rational numbers, including the notation for fractions. Next, we show the types of writing for fractions.

Final notation for fractions
The fraction notation used today was first presented by Leonardo of Pisa in (1202), who was also known as Leonardo Fibonacci. He was also known for discovering the Fibonacci sequence. Below we present the work, in which he mentioned fraction notation.
