>Hello Sohib EditorOnline, in this article, we will discuss how to add common fractions in a simple and easy way. Fractions may seem complicated, but with the right approach, you can easily add them up. Let’s get started!

What are Common Fractions?

A common fraction is a number that represents part of a whole. It consists of a numerator, which is the number above the line, and a denominator, which is the number below the line. For example, 1/2, 2/3, and 3/4 are all common fractions.

When adding common fractions, we need to make sure that the denominators are the same. If the denominators are different, we need to find a common denominator before adding the fractions.

Example:

If we want to add 1/2 and 1/3, we need to find a common denominator. The common denominator for 2 and 3 is 6. We can convert 1/2 to 3/6 and 1/3 to 2/6, then add them together as follows:

Numerator Denominator
1/2 3 6
+
1/3 2 6
= 5 6

Therefore, 1/2 + 1/3 = 5/6.

How to Find a Common Denominator?

When adding fractions with different denominators, we need to find a common denominator. There are two methods to find a common denominator:

Method 1: Multiply the Denominators

The first method is to multiply the denominators together. This will give us a common multiple of both denominators. However, this method may not always give us the smallest common denominator.

Example:

If we want to add 1/2 and 1/3, we can multiply the denominators together to get a common denominator of 6 as shown below:

Numerator Denominator
1/2 3 6
+
1/3 2 6
= 5 6

Therefore, 1/2 + 1/3 = 5/6.

Method 2: Find the Least Common Multiple

The second method is to find the least common multiple (LCM) of the denominators. The LCM is the smallest number that is a multiple of both denominators. This method will give us the smallest possible common denominator.

Example:

If we want to add 1/2 and 2/5, the denominators are 2 and 5. The multiples of 2 are 2, 4, 6, 8, 10, 12, … and the multiples of 5 are 5, 10, 15, 20, 25, 30, … The LCM of 2 and 5 is 10, which is the smallest multiple that both denominators have in common. We can convert 1/2 to 5/10 and 2/5 to 4/10, then add them together as follows:

Numerator Denominator
1/2 5 10
+
2/5 4 10
= 9 10

Therefore, 1/2 + 2/5 = 9/10.

How to Add Common Fractions?

Once we have found a common denominator, we can add the fractions by adding the numerators together and keeping the denominator the same.

Example:

If we want to add 3/4 and 1/4, the denominators are already the same. We can simply add the numerators together as follows:

Numerator Denominator
3/4 3 4
+
1/4 1 4
= 4 4

Therefore, 3/4 + 1/4 = 1.

What if the Result is an Improper Fraction?

Sometimes, the result of adding fractions may be an improper fraction, which means the numerator is greater than or equal to the denominator. In this case, we need to simplify the fraction by dividing both the numerator and the denominator by their greatest common factor (GCF).

Example:

If we want to add 5/6 and 2/3, we can find a common denominator of 6 as shown below:

Numerator Denominator
5/6 5 6
+
2/3 4 6
= 9 6

The result is an improper fraction, 9/6. To simplify the fraction, we need to find the GCF of 9 and 6, which is 3. We divide both the numerator and the denominator by 3 to get the simplified fraction:

Numerator Denominator
9/6 9 ÷ 3 = 3 6 ÷ 3 = 2
= 3 2

Therefore, 5/6 + 2/3 = 3/2.

Conclusion

Adding common fractions may seem challenging, but with the right approach, it can be done easily. Remember to find a common denominator, add the numerators, and simplify the result if necessary by dividing both the numerator and the denominator by their GCF.
