The number below the bar in a fraction is called the Denominator.
We can also define denominator as the number of parts that a whole is divided into.
A fraction with zero (0) in the denominator is undefined.
The given circle is divided into 3 parts. Out of the 3 parts, one part is shaded.
So, we write this model as in fraction form.
In this fraction 3 is the denominator whereas 1 is the numerator.
