Numerator and Denominator

What are the numerator and denominator of a fraction?

We have already learnt that a fraction is written with two numbers arranged one over the other and separated by a line. The number under the line shows in how many equal parts the whole has been divided into. It is called denominator of the fraction. The number above the line shows how many parts of the whole have been taken. It is called numerator of the fraction. So in 2/3, 2 is the numerator and 3 is the denominator.

Numerator and Denominator of a Fraction:

We can see that a fraction has two parts.

The number above the division line and the number below the division line. The number below the division line tells us into how many equal parts single or collection of object has been divided. We call it the Denominator. The number above the division line tells us how many of these equal parts have been

taken from the whole. We call it the Numerator.

Read as 2 over 5 or two by five.
