Definition and example of fraction
A fraction is a number which represents a part of a whole.
Fractions in Maths helps us to measure how many parts are there and the size of each part of an object.
Let’s see how to read fractions with examples.
This is read as five – elevenths.
means 3 parts are taken from equally divided 8 parts of whole.
Fractions are always positive, that means numerator and denominator are positive integers.
The Denominator can never be zero in a fraction.
Which are 10 types of fractions?
There are many types of fractions but the commonly used ten types of fractions are:
- Unit fraction
- Like fractions
- Unlike fractions
- Simple fraction
- Complex fraction
- Decimal fraction
- Vulgar fraction
- Proper fraction
- Improper fraction
- Mixed fraction
1. Unit fraction
A fraction whose numerator is one and denominator can be any positive integer is called a Unit fraction.
,
,
etc.
In , the numerator is 1 and denominator 4 which is a
positive integer.
2. Like fractions
The fractions which have the same denominator are called Like fractions.
,
,
etc.
So, the above fractions
,
and
have the same denominator i.e.
9, so they are like fractions.
3. Unlike fractions
The fractions which have different denominators are called Unlike fractions.
,
,
,
etc.
So, the above fractions
,
,
and
have different
denominators i.e. 9, 4, 11 and 8 respectively, so they are Unlike fractions.
4. Simple fraction
A fraction whose both terms are integers is called a simple fraction.
, etc.
5. Complex fraction
A fraction whose one or both terms are fractional numbers is called complex fraction
,
6. Decimal fraction
Fractions whose denominators are 10, 100, 1000 etc. are decimal fractions.
7. Vulgar fraction
Fractions whose denominators are not 10, 100, 1000 etc. are called vulgar fractions.
8. Proper fraction
A fraction whose numerator is positive and also less than its denominator is called proper fraction.
9. Improper fraction
A fraction whose numerator is greater than its denominator is called improper fraction.
10. Mixed fraction
A fraction which is expressed as a combination of integer and a proper fraction is called mixed fraction.
What is an equivalent fraction?
The two or more than two fractions are said to be equivalent when multiplying the numerator and denominator by a same non zero positive number results in the original fraction.
Let’s take an example of
Multiply both numerator and denominator by 1:
Multiply both numerator and denominator by 2:
Multiply both numerator and denominator by 3:

How to show fractions with shaded diagram
Fractions can be shown with shaded area in a diagram also. The numerator in a fraction is shown as shaded area and the denominator is the total number of cut pieces in the diagram.
In general, a fraction can be changed into the shaded diagram with the following method.
Fraction =
Let’s see with examples how to shade the area for fractions.
Example 1. Fraction
The fraction
The numerator 1 of fraction
So, the above diagram refers the 1 part out of 2 equal parts.
Example 2. Fraction
The numerator 1 of fraction
So, the above diagram refers the 1 part out of 3 equal parts.
Example 3. Fraction
Fractions can also be represented with a circle and dividing it into equal sectors, equal to
denominator of the fraction and number of shaded sectors equal to the numerator of the fraction.
So, here, total number of sectors in the circle = 4
and number of shaded sectors in the circle = 2
So, the above diagram refers the 2 part out of 4 equal parts.
Example 4. Fraction
Total number of boxes = 3
and number of shaded boxes = 0
So, the above diagram refers the 0 part out of 3 equal parts.
Example 5. Fraction
Total number of boxes = 3
and number of shaded boxes = 3
So, the above diagram refers the 3 part out of 3 equal parts.
Example 6. Fraction
Total number of boxes = 10
and number of shaded boxes = 4
So, the above diagram refers the 4 part out of 10 equal parts.
Real life example of fractions
A pizza bought from market and sharing with 8 friends equally is a real life example of fractions. The pizza is going to be divided into eight equal pieces assuming that everyone will share one equal piece.
So, a pizza has been cut into total equal pieces of 8 to divide among 8 friends.
We can write the one piece of pizza in fractions as
In fractions we can say one friend is sharing
What we have learnt about fractions from above is that a fraction has a numerator and a denominator. The denominator keeps the value of the total number of parts and numerator holds the value of a part of the whole object.
Hence, we can write in fractions
How the fraction is written, if one person is absent out of 8, eventually any one friend will get an opportunity to have 2 pieces of it. So finally we have 7 friends and 8 cut pieces of pizza.
The friend who will get 2 pieces of pizza, in fractions it can be written as
The remaining 6 friends share 1 piece, so their fraction of pizza shared still remains as
