Fraction | Term 2 Chapter 6
What is a Fraction?
A fraction is how many part or parts of a whole we have.
$$ \text{Fraction} = \frac{\text{Numerator}}{\text{Denominator}} = \frac{\text{Collected portion}}{\text{Divided portion}} $$
Example: Swathi's Birthday
Swathi is studying fourth standard, today is her birthday. So the whole class bought a birthday cake for her. In front of her class teacher and students, Swathi cuts her birthday cake. In her class 19 students and a teacher. So she cuts the cake.
Teacher: Students, you bought a cake, here cake is a whole part. Swathi divided the whole into 20 equal parts, everybody had a part (piece).
A piece of cake given to one student is one out of twenty. We can write it as:
$$ \frac{1}{20} $$
If we have numbers $$ \frac{1}{20} $$ like this, then we Call it as fraction.
In $$ \frac{1}{20} $$, 1 is numerator, 20 is denominator.
Thus Combination of number like numerator and denominator is called as fraction.
Observe the Following Pictures
A circle is divided into four equal parts. In this four parts only one part is shaded.
The shaded portion is fraction = $$ \frac{1}{4} $$ (or) one fourth.
The whole portion was divided into two equal parts. In this two parts one part is coloured or shaded. The shaded parts fraction = $$ \frac{1}{2} $$ (half).
The whole portion was divided into three equal parts. In that two parts are shaded. The shaded parts fraction = $$ \frac{2}{3} $$ (two third).
The whole portion was divided into four equal parts. In that two parts are shaded. The shaded parts fraction = $$ \frac{2}{4} $$ (two fourth).
The whole portion was divided into eight equal parts. In that three parts are shaded. The shaded portion’s fraction = $$ \frac{3}{8} $$ (Three eighth).
$$ \frac{1}{2}, \frac{2}{3}, \frac{2}{4}, \frac{3}{8} $$
Such numbers are examples for fraction.
