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.
