Numerator and Denominator of a Fraction

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 \(\frac{2}{3}\), 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.

Fraction mean part of a region or part of a collection.

  \(\frac{3}{8}\)     \(\frac{\textrm{coloured mangoes}}{\textrm{mangoes in all}}\) 

  \(\frac{3}{8}\)     \(\frac{→}{→}\)     \(\frac{\textrm{Numerator}}{\textrm{Denominator}}\)

Answer:

VII. (i) \(\frac{30}{5}\)

(ii) \(\frac{9}{54}\)

(iii) \(\frac{15}{30}\)

VII. Write the fraction with:

Answer:

VIII. (i) \(\frac{2}{5}\)

(ii) \(\frac{4}{10}\)

(iii) \(\frac{3}{7}\)

(iv) \(\frac{1}{6}\)

(v) \(\frac{4}{8}\)

The number above the line is called the 'numerator' of the fraction and the number below the line is called the 'denominator' of the fraction.

For example, in fraction \(\frac{7}{12}\), 7 is the numerator and 12 is the denominator.

Also, in fraction \(\frac{3}{8}\), 3 is the numerator 8 is the denominator.
