Fractions 
Introduction
? In this chapter we shall learn about a new kind of 
numbers, called fractions.
? Fractions are number that represent a part of the 
whole.
? Imagine you have a pizza and you want to divide it 
amongst 4 friends. So how much would each of you 
get?
? Each of you would get a part of the whole pizza, and 
adding all of it together would give you back the pizza.

Fractions and Pizzas 
? To represent such numbers we use fractions. In this case 
each of you would get 1/4 of the whole pizza. This is called 
one-fourth. 
? Denominator represents the total available entities, 
whereas numerator represents the entity that is selected !

Notation
? A fraction is usually denoted as ‘a/b’, where ‘a’ and ‘b’ 
are integers and ‘ a’ is called the numerator and ‘b’ is 
called the denominator.
? So 2/5 means a thing that is divided into 5 parts and 
we take 2 out of those 5 parts.
? Similarly 9/23 means a thing has been divided into 23 
parts and we take 9 parts out of those 23 parts.

Number Line representation
? Like integers we can represent fractions also in 
terms of a number line.
? For example to show 1/5 in a number line, we first 
divide the portion between 0 and 1 into five parts 
and then take the first part as 1/5.
? Similarly we can show the other fractions.
