How to Add Fractions with Different Denominators Step by Step
FAQs on Adding Unlike Fractions for Class 6 (Denominators 2–12)
1. How do you add fractions with different denominators?
To add fractions with different denominators, you must first find a common denominator and convert them into equivalent fractions before adding the numerators. This process is essential for solving problems with unlike fractions.
The key steps are:
- Find the Common Denominator: First, find the Least Common Multiple (LCM) of the different denominators.
- Create Equivalent Fractions: Convert each fraction into an equivalent one using the LCM as the new denominator.
- Add the Numerators: Add the numerators of the newly formed equivalent fractions.
- Simplify: Keep the denominator the same and simplify the resulting fraction to its lowest terms if necessary.
2. What are unlike fractions?
Unlike fractions are fractions that have different denominators. Before you can perform addition or subtraction on them, you must convert them into like fractions by finding a common denominator.
For example:
- The fractions 1/3 and 1/5 are unlike fractions because their denominators (3 and 5) are different.
- The fractions 2/7 and 5/7 are like fractions because they share the same denominator.
3. What is the easiest way to find a common denominator?
The easiest and most accurate method to find a common denominator for Class 6 Maths is to calculate the Least Common Multiple (LCM) of the denominators. Using the LCM ensures you work with the smallest possible numbers, making calculations simpler.
For example, to add 1/6 + 1/8:
- Multiples of 6 are 6, 12, 18, 24, 30...
- Multiples of 8 are 8, 16, 24, 32...
- The LCM is 24, which becomes the common denominator.
4. What is an example of adding unlike fractions?
A common example of adding unlike fractions for Class 6 is solving a sum like 1/3 + 1/4. To solve this, you find a common denominator, create equivalent fractions, and then add.
Here is the step-by-step solution:
- Step 1: Find the LCM of the denominators 3 and 4, which is 12.
- Step 2: Convert 1/3 to an equivalent fraction with a denominator of 12 (1/3 = 4/12).
- Step 3: Convert 1/4 to an equivalent fraction with a denominator of 12 (1/4 = 3/12).
- Step 4: Add the numerators: 4/12 + 3/12 = 7/12.
5. How do you add fractions step by step for Class 6?
To add fractions step-by-step for Class 6, especially when they have different denominators, you need to follow a clear four-step process. This method ensures you correctly solve any problem involving the addition of unlike fractions.
The steps are:
- Find the Least Common Multiple (LCM) of the denominators. This will be your new common denominator.
- Convert each fraction into an equivalent fraction that has the LCM as its denominator.
- Add the numerators of the new, equivalent fractions.
- Write the sum of the numerators over the common denominator and simplify the fraction if possible.

The benefits of using the LCM are:
- It makes converting to equivalent fractions easier.
- It results in a final answer that is simpler to reduce or is already in its simplest form.
- It is the most efficient method taught in the Class 6 maths syllabus for handling fractions with different denominators.
