Answer:
What is Fraction?
Fractions represent equal parts of a whole or a collection.
Fraction of a whole: When we divide a whole into equal parts, each part is a fraction of the whole.
For example,
Fraction of a Whole
Fraction of a Whole
Fraction of a collection: Fractions also represent parts of a set or collection.
For example,
There are total of 5 children.
3 out of 5 are girls. So, the fraction of girls is three-fifths ( 3⁄5 ).
2 out of 5 are boys. So, the fraction of boys is two-fifths ( 2⁄5 ).
Fraction notation
A fraction has two parts. The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken. The number below the line is called the denominator. It shows the total divisible number of equal parts the whole into or the total number of equal parts which are there in a collection.

Fun Facts
The word ‘fraction’ has been derived from the Latin ‘fractus’ which means “broken”.
Fraction has been into existence from the Egyptian era which is known to be one of the oldest civilizations in the world. However, fractions were not regarded as numbers, in fact, they were used to compare the whole numbers with one another.
