What is a Fraction?

  • Fraction is a part of a whole or a part of a collection.

  • Fraction has two parts.

(i) Numerator

(ii) Denominator


Fraction Formula


Fraction Formula

  • 4 one-fourth make a whole.

Combination of quarters


Combination of quarters


Solved Example: Find the fraction of the coloured part in the shape.

Representation of fraction


Representation of fraction

  1. $\frac{4}{8}$

  1. $\frac{5}{8}$

  2. $\frac{3}{8}$

  3. $\frac{6}{8}$

Ans: There is a total of 8 parts so the denominator of fraction = 8.

We want to find the fraction of the coloured parts.

There is a total of 3 coloured parts so the numerator of fraction = 3.

So the required fraction = $\frac{3}{8}$.

Therefore, Option (C) is correct.


Fraction of a Group

  • The fraction of a group is written as fraction x Group.

Solved Example 1: Find the value of one-Sixth of 48.

Ans: One-Sixth = $\frac{1}{6}$

The value of one-Sixth of 48 = $\frac{1}{6}\times 48=8$


Types of Fractions

1. Like Fractions

Fractions which have the same denominators are known as Like fractions.


Solved Example: Which of the following pairs of fractions are like fractions?

  1. $\frac{4}{8}$ and $\frac{5}{7}$

  1. $\frac{5}{7}$ and $\frac{5}{6}$

  2. $\frac{3}{5}$ and $\frac{2}{5}$

  3. $\frac{6}{8}$ and $\frac{5}{7}$

Ans: Fractions which have the same denominators are known as Like fractions.

  • For option A, ($\frac{4}{8}$ and $\frac{5}{7}$) denominators are not the same so these are not like fractions.

  • For option B, ($\frac{5}{7}$ and $\frac{5}{6}$) denominators are not the same so these are not like fractions.

  • For option C, ($\frac{3}{5}$ and $\frac{2}{5}$) denominators are the same so these are like fractions.

  • For option D, ($\frac{6}{8}$ and $\frac{5}{7}$ ) denominators are not the same so these are not like fractions.

Therefore, Option (C) is correct.


2. Unlike Fractions

Fractions which have different denominators are known as the Unlike fractions.


Solved Example: Which of the following pairs of fractions are unlike fractions?

  1. $\frac{4}{8}$ and $\frac{5}{8}$

  1. $\frac{5}{7}$ and $\frac{6}{7}$

  2. $\frac{3}{5}$ and $\frac{2}{5}$

  3. $\frac{6}{8}$ and $\frac{5}{7}$

Ans: Fractions which have different denominators are known as the Unlike fractions.

  • For option A, ($\frac{4}{8}$ and $\frac{5}{8}$) denominators are the same so these are not unlike fractions.

  • For option B, ($\frac{5}{7}$ and $\frac{6}{7}$) denominators are the same so these are not unlike fractions.

  • For option C, ($\frac{3}{5}$ and $\frac{2}{5}$) denominators are the same so these are unlike fractions.

  • For option D, ($\frac{6}{8}$ and $\frac{5}{7}$) denominators are not the same so these are unlike fractions.

Therefore, Option (D) is correct.


3. Proper Fractions

  • Fractions having numerators smaller than the denominator are known as Proper fractions.

  • Proper Fractions have value less than 1.


Solved Example: Which of the following fractions is a proper fraction?

  1. $\frac{9}{8}$

  2. $\frac{10}{8}$

  3. $\frac{11}{8}$

  4. $\frac{6}{8}$

Ans: Fractions having numerators smaller than the denominator are known as Proper fractions.

In option D, the numerator is 6 and the denominator is 8. So the numerator is less than the denominator.

Therefore $\frac{6}{8}$ is a proper fraction.

Therefore, Option (D) is correct.


4. Improper Fractions

  • Fractions having numerators greater than the denominator are known as Improper fractions.

  • Improper Fractions have a value as 1 or greater than 1.


Solved Example: Which of the following fractions is an improper fraction?

  1. $\frac{5}{8}$

  2. $\frac{10}{8}$

  3. $\frac{4}{8}$

  4. $\frac{6}{8}$

Ans: Fractions having numerators greater than the denominator are known as improper fractions.

In option B, the numerator is 10 and the denominator is 8. So the numerator is greater than the denominator. 

Therefore $\frac{10}{8}$ is an improper fraction.

Therefore, Option (B) is correct.


5. Mixed Fractions

  • The combination of a whole number and a fraction is known as a Mixed fraction.

Solved Example: Convert $\frac{5}{3}$ into Mixed fractions.

Ans: The combination of a whole number and a fraction is known as a Mixed fraction.

We will divide the numerator by the denominator and the quotient will be the whole number and the remainder will be the numerator of the fraction of mixed fraction and the denominator will be the same.

If we divide 5 by 3 then the quotient will be 1 and the remainder will be 2.
$\frac{5}{3}$ =1$\frac{2}{3}$

Equivalent Fractions

  • Equivalent fractions are the fractions with different numerators and denominators but have the same value.

  • To get equivalent fractions, multiply the numerator and denominator of the fraction by the same number.


Solved Example 1: Write the equivalent fractions of $\frac{1}{2}$.

Ans: To write the equivalent fraction of a fraction, we have to multiply the numerator and denominator of the fraction by the same number.

We have to write the equivalent fraction of $\frac{1}{2}$.

We will multiply the numerator and denominator by 2.

Equivalent fraction = $\frac{1}{2}\times\frac{1}{2}$.

Equivalent fraction = $\frac{1}{2}$


Solved Examples 2: Which of the following is an equivalent fraction of $\frac{3}{7}$?

  1. $\frac{6}{7}$

  1. $\frac{6}{14}$

  2. $\frac{3}{7}$

  3. $\frac{3}{14}$

Ans: To write the equivalent fraction of a fraction, we have to multiply the numerator and denominator of the fraction by the same number.

We have to write the equivalent fraction of $\frac{3}{7}$.

We will multiply the numerator and denominator by 2.

Equivalent fraction = $\frac{3}{7}\times\frac{2}{2}$.

So, equivalent fraction = $\frac{16}{4}$.

Therefore, Option (B) is correct.


Comparing Like Fractions

  • In Like fractions, the denominators are the same therefore we can compare like fractions by comparing their numerators only.

  • The fraction with a greater numerator is greater.


Solved Example: Check whether $\frac{3}{5}$is greater than $\frac{2}{5}$or not.

Ans: If we compare $\frac{2}{5}$and $\frac{3}{5}$then we will compare numerators only. 

Here 3 is greater than 2, therefore $\frac{3}{5}$is greater than $\frac{2}{5}$.


Comparing Unlike Fractions(Same Numerators)

  • For Unlike fractions, denominators are different but numerators can be the same or different.

  • If Numerators are the same then compare denominators only.

  • The fraction with a smaller denominator is greater.


Solved Example: Check whether $\frac{2}{5}$is greater than $\frac{2}{7}$or not.

Ans: If we compare $\frac{2}{5}$ and $\frac{2}{7}$ then we will compare denominators only. 

Here 5 is smaller than 7, therefore $\frac{2}{5}$is greater than $\frac{2}{7}$.


Comparing Unlike Fractions(Different Numerators)

  • If Numerators are different then first we need to convert unlike fractions into like fractions.

  • To convert unlike fractions into like fractions there are a few steps which are given below.

Step 1: Take the LCM of denominators(LCM is the smallest number divisible by both numbers).

Step 2: Change the fractions to the equivalent fraction with the same denominator.


Solved Example: Check whether $\frac{2}{5}$ is greater than $\frac{3}{10}$ or not.

Ans: If we compare $\frac{2}{5}$ and $\frac{3}{10}$ then we will take the LCM of denominators. 

So LCM of 5 and 10 we will find as:

5=5 x 1 

10=5 x 2

LCM(5, 10) =5 x 2 x 1=10

So one denominator is already equal to 10 and another we will convert using an equivalent fraction.

$\frac{2}{5}\times\frac{2}{2}-\frac{4}{10}$

Now both fractions are like fractions, so we can simply compare numerators.

Here 4 is greater than 3, therefore $\frac{2}{5}$is greater than $\frac{3}{10}$.
