A fraction represents a part of a whole. It has two parts: numerator and denominator. In this post, we will learn how to simplify a fraction in its lowest forms.
A fraction is always of the form:
$\dfrac{p}{q}$
where p and q are integers with q≠0.
Steps to Simplify Fractions
Let us consider a fraction $\dfrac{p}{q}$. The below steps have to be followed in order to simplify the fraction p/q in the lowest terms.
- Step 1: Note that the numerator is p and the denominator is q. First, check whether p and q have common factors or not.
- Step 2: If they do not have a common factor other than 1, then the given fraction $\dfrac{p}{q}$ is already in the lowest terms.
- Step 3: If they have common factors other than 1, then note down the greatest common factor (GCF).
- Step 4: Put d:= GCF(p, q).
- Step 5: Divide both p and q by d, the resulting fraction will be the simplified form of the given fraction which is $\dfrac{p \div d}{q \div d}$.
Let us now understand the above procedure to get a simplified reduced fraction with an example.

Examples of Simplifying Fractions
Example 1:
Let us simplify the fraction 2/4.
Here the numerator is 2 and the denominator is 4.
Factors of 2 are 1, 2.
Factors of 4 are 1,2, 4.
So the greatest common factor (GCF) of 2 and 4 is 2, that is, GCF(2,4) = 2. So the simplified form of 2/4 is given as follows:
$\dfrac{2 \div 2}{4 \div 2}$ = $\dfrac{1}{2}$
Thus, 1/2 is the reduced lowest form of 2/4.
Example 2:
We will now simplify the fraction 1/3.
See that 1 and 3 do not have common factors other than 1.
So by the above method of simplifying fractions, we can conclude that 1/3 is already in its lowest form.
FAQs
Q1: How to simplify a fraction?
Answer: To simplify a fraction, we need to divide both the numerator and the denominator by their greatest common divisor. For example, let us simplify 3/6. Note that the greatest common divisor of 3 and 6 is 3. So (3÷3)/(6÷3)=1/2 is the simplified form of 3/6.
