More About Fraction Notation

In a fraction, the number written above the bar is called "numerator" and the one written below the bar is called "denominator".

Example of Fraction Notation

 In the given figure, 5 out of 8 flowers are shaded.
To write the fraction notation of the shaded part, we first note the numerator and denominator.
Total number of parts will be written as the denominator.
Number of parts that are shaded will be the numerator. 
Here, 5 out of 8 flowers have been shaded.
So, 5 is the numerator and 8 is the denominator. 
So, we write the fraction as 5/8.
