Definition:

In mathematics, whole numbers are the set of numbers {0, 1, 2, 3, 4, 5β¦β¦.}. A fraction is defined as a part of a whole number that has been divided into an equal number of parts.

A fraction is written as π / π  where a and b are whole numbers. a is known as the numerator and b is known as the denominator. Note that the denominator cannot be equal to zero.

In the above figure (a), the rectangle is divided into 4 equal parts. One of these parts is shaded. Hence, the shaded portion is represented by the fraction 1/4

Similarly, in figure (b) the shaded portion is represented by the fraction 3/8

In figure (c) the shaded portion is represented by the fraction 2/4 which is the same as 1/2

Types of fractions

β Proper fractions

If the numerator of a fraction is less than its denominator then the fraction is known as a proper fraction.

For example: 3/8 , 1/7 , 5/12 are all proper fractions as the numerator is less than the denominator in each of these fractions.

β Improper fractions

If the numerator of a fraction is greater than or equal to its denominator then the fraction is known as an improper fraction.

For example: 8/3 , 12/7 , 15/2 are all improper fractions as the numerator is greater than the denominator in each of these fractions. Each of these fractions has a value more than 1.

β Mixed fractions

A mixed fraction is the combination of a whole number and a proper fraction. Improper fractions can be converted to mixed fractions and vice versa

For example:   are all mixed fractions as they include a whole number and a proper fraction.

You can convert an improper fraction to a mixed fraction by dividing the numerator by the denominator.

Mixed fraction can now be obtained as :

Similarly, you can convert a mixed fraction into an improper fraction by using the formula

β Like fractions

When two or more fractions have the same denominator, they are referred to as like fractions.

For example: 3/8 , 5/8 , 1/8 all have the same denominator 8 and are thus like fractions.

β Unlike fractions

When two or more fractions have different denominators, they are referred to as unlike fractions.

β For example: 3/8 , 1/7 , 5/12 all have different denominators and are thus unlike fractions.
