Can You Add Fractions With Different Denominators

Fortunately, learning to add fractions with like and good (different) denominators is a relatively simple process. This free How to Add Fractions step-by-step guide will teach you how to add fractions with the same denominator and how to add fractions with different denominators using a simple and easy 3-step process.

But, before you learn how to add fractions, let’s quickly review some key features and vocabulary terms related to fractions before moving on to some step-by-step examples of how to add fractions.

Can You Add Fractions With Different Denominators

To learn how to add fractions, you need to understand the difference between the numerator and the denominator.

Definition: The numerator of a fraction is the top number in the fraction. For example, in the fraction 3/4, the denominator is 4.

Definition: The denominator of a fraction is the smallest number in the fraction. For example, in the fraction 3/4, the denominator is 4.

Very simple, isn’t it? These terms are clearly shown in Figure 01 below. Make sure you understand the difference between the numerator and denominator of a fraction before continuing with this guide. If you mix them up, you won’t learn how to add fractions correctly.

Now that you know the difference between the numerator and denominator of a fraction, you’re ready to learn how to identify which of the following categories a problem in adding fractions falls into:

Can You Add Fractions With Different Denominators

Fractions with the same denominator have fewer numbers of the same value. For example, in the case of 1/5 + 3/5, you are adding fractions with the same denominator because the denominator in both fractions is 5.

In contrast, fractions with opposite (or opposite) denominators have fewer numbers that do not equal the same value. For example, in the case of 1/2 + 3/7, you’re adding fractions with different denominators because the fractions don’t have a common denominator (one has a denominator of 2 and the other has a denominator of 7).

How To Add Fractions With The Same Denominator

Figure 02: To learn how to add fractions, you must be able to recognize when fractions have the same denominator and when they have different denominators.

Again, this concept should be simple, but a quick review is necessary because in order to solve it correctly you have to be able to identify whether a difference addition problem involves like or opposite denominators.

Can You Add Fractions With Different Denominators

Our first example is fairly simple, but it’s perfect for learning how to use our easy 3-step process, which you can use to solve any problem involving adding fractions:

How To Add Fractions With Different Denominators

Well, let’s first try using these steps to solve the first example: 1/4 + 2/4 = ?

Can You Add Fractions With Different Denominators

Step Two: If they are the same, go to Step Three. If they differ, find a common denominator.

To complete this first example, simply add the numbers together and express the result as a single fraction with the same denominator:

As you can see from this first example, learning how to add fractions with the same denominator is very simple.

Before learning how to add fractions with different denominators, let’s look at another example of adding fractions with the same denominator.

Can You Add Fractions With Different Denominators

To solve this second example, let’s apply the same 3-step process we did in the previous example:

In this case, 6/9 is the correct answer, but this fraction can actually be reduced. Since 6 and 9 are both divisible by 3, 6/9 can be reduced to 2/3.

Can You Add Fractions With Different Denominators

For this example, you cannot skip the second step. Before continuing, you’ll need to find a common denominator—a number that both denominators can divide evenly.

An easy way to do this is to multiply the denominator of the first fraction by the second fraction and the denominator of the second fraction by the first fraction (i.e. multiply the denominators together).

Fig. 05: How to add fractions with different denominators: Multiply the denominators together to find the common denominator.

Now, we’ve changed the original question to a scenario that involves adding two fractions with common denominators, which means the hard work is done and we can solve by adding the numerators and keeping the denominators the same:

As in the previous example, the second step is to find a common denominator by multiplying the denominators together as follows:

How To Subtract Fractions

To add fractions with the same denominator, simply add the numerator (top value) and keep the denominator (bottom value) the same.

To add fractions with different denominators, you need to find the common denominator. A common divisor is a number that can be divided equally by both the denominators.

Adding And Subtracting Fractions With Unlike Denominators Worksheet

Adding or adding fractions is one of the basic operations that allows two or more fractions to be added to an equal number, which is called “sum” or “the result of addition”.

Can You Add Fractions With Different Denominators

The addition of fractions is represented by a crossed “+” sign, also known as a “plus”.

To get a numerical value as a fraction, you must first identify whether the sum of the fractions has a common denominator or a different denominator, so there are two processes:

It is also called sum of fractions with like denominators or sum of like fractions, it is the simplest and simplest process, because the addition process is based on adding the numerators and the denominator remains the same.

Since we can simplify equations to sum fractions, also known as sum of odd denominators or odd fractions, it is recommended to know how to find the least common multiple (LCM).

Can You Add Fractions With Different Denominators

Two different methods are considered for sum of fractions with different denominators, in this case, the first method corresponds directly as we cannot obtain the least common multiple of the denominator and the second method obtains the least common multiple. corresponds to doing.

How To Subtract Fractions In 3 Easy Steps — Mashup Math

A) Method of dividing the denominators by arithmetic: It involves finding the common denominator of the fractions to be added. For example:

Can You Add Fractions With Different Denominators

B) Cross multiplication method: It involves finding the common denominator of the fractions to be added. For example:

Second Method: This involves finding the least common multiple of the denominator, it is enough to identify the greatest common multiple between them to make the sum of the fractions. To add fractions to the denominator with multiplication, the following procedure is followed, taking addition as an example:

Awesome Activities For Adding And Subtracting Fractions With Like Denominators

Note: This method is recommended to be learned, as it allows you to simplify simple fraction equations.

This process is similar to adding two fractions, except you must first identify whether their denominators are common. If the denominators are the same, we can sum by adding the numerators, which corresponds to the “sum of fractions with like denominators” method. If the denominators are different, then the least common product of the denominators must be obtained that corresponds to the “sum of fractions with different denominators” method.

Can You Add Fractions With Different Denominators

Having the same denominators simplifies the process because the denominators are the same and the numerators need to be added.

Classic Mistakes: Adding Fractions

Since there are three or more fractions with different denominators, it is recommended to use method 2 of “summing fractions with different denominators” to simplify the equation and get the correct result. Example:

Can You Add Fractions With Different Denominators

1.- Identify the least common factor of the fractions to be added, the denominator 12 is a product of 3 and 4, the number 12 is the greatest common factor.

3.- The result of the quotient is multiplied by the quotient of the same quotient: 4×2 = 8.

4.- Once it is divided and multiplied, the result is placed in a digit with the sign of the fraction, in this case the numerator is positive but it is worth keeping the sign.

5.- The same process is done with other fractions and sum is done with the results.
