Cómo realizar la suma de tres fracciones con denominadores diferentes

Step 1: Find a Common Denominator

One of the first steps in solving a fraction problem is to find a common denominator. A common denominator is a number that can be divided evenly by the denominators of all the fractions involved.


Step 2: Convert the Fractions

In this step, we will learn how to convert fractions from one form to another. Converting fractions is an important skill in mathematics as it allows us to compare and perform calculations with fractions more easily.

Converting proper fractions to decimals:

To convert a proper fraction (a fraction where the numerator is less than the denominator) to a decimal, we divide the numerator by the denominator. The result is a decimal representation of the fraction.



We want to convert the fraction 3/4 into a decimal. We divide 3 by 4: 3 ÷ 4 = 0.75. Therefore, 3/4 as a decimal is 0.75.

Converting mixed numbers to improper fractions:


A mixed number is a whole number combined with a proper fraction. To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction, then add the numerator. The result becomes the new numerator, and the denominator remains the same.


We want to convert the mixed number 2 1/3 into an improper fraction. First, we multiply 2 (the whole number) by 3 (the denominator) and add the numerator 1. The result is 7. Therefore, 2 1/3 as an improper fraction is 7/3.

Converting improper fractions to mixed numbers:

An improper fraction is a fraction where the numerator is equal to or greater than the denominator. To convert an improper fraction to a mixed number, we divide the numerator by the denominator. The whole number part of the division is the whole number of the mixed number, and the remainder becomes the numerator of the fraction. The denominator remains the same.


We want to convert the improper fraction 8/5 into a mixed number. We divide 8 by 5: 8 ÷ 5 = 1 remainder 3. Therefore, 8/5 as a mixed number is 1 3/5.

Converting fractions allows us to work with them more easily in calculations and comparisons. Practice converting fractions to become more comfortable with this important skill!

Step 3: Add the Numerators

In this step, we will focus on adding the numerators. This is a crucial part of the process, as it allows us to determine the final value of the fraction.

Before we begin, let’s define what a numerator is:

A numerator is the number on top of a fraction, which represents the total number of parts we are considering.

Now, let’s use an example to better understand how to add the numerators:


Consider the fraction 3/4.

In this case, the numerator is 3.

To add the numerators, we need to follow these steps:

  1. Identify the numerators of the fractions you want to add.
  2. Add the numerators together.

Let’s apply these steps to the example:

  1. The numerators we want to add are 3.
  2. Adding 3 to itself gives us a sum of 6.

So, when adding the numerators of the fraction 3/4, we get a sum of 6.

Remember, the numerator represents the total number of parts we are considering, and adding the numerators is an essential step in determining the final value of a fraction.

Step 4: Simplify the Result

In the fourth step of the process, it is crucial to simplify the result to ensure clarity and effectiveness. By simplifying the information, it becomes easier for readers to understand and absorb the key points.

One effective way to emphasize important phrases in the text is by using the HTML strong tags. These tags allow you to highlight specific words or phrases, instantly drawing the readers’ attention.

For example, imagine you have a sentence like this: “The main advantage of this product is its versatility.” To emphasize the importance of versatility in this sentence, you can use the strong tags like this: “The main advantage of this product is its versatility.”

In addition to using the strong tags, you can also make use of HTML headings, such as the H3 tag. Headings not only add structure to your content but also help break down the information into manageable sections. By using clear and concise headings, you make it easier for readers to skim through the text and locate the specific information they need.

Moreover, utilizing HTML lists can enhance the readability of your content. Lists provide a visually organized format by allowing you to present information in bullet points or numbered sequences. This format helps to highlight key details and create a more structured and easily digestible article.

Lastly, in addition to using the strong tags, H3 headings, and HTML lists, you can also consider using the bold tags () to further emphasize important keywords or phrases. However, it is essential to use the bold tags sparingly and only when necessary, as excessive use can make the text visually overwhelming and difficult to read.

In conclusion, when simplifying the result in your content, the use of HTML strong tags, H3 headings, and HTML lists can greatly enhance the readability and effectiveness of your text. By properly emphasizing important phrases and organizing the information, you can ensure that your readers can easily understand and retain the key points of your content.

Step 5: Finalize the Answer

In this step, we will focus on finalizing the answer to the question at hand. To do this, we need to highlight the most important phrases and improve the overall formatting of our response.

First, let’s start by making the key phrases more prominent using the <strong> </strong> tags. This will make them stand out and draw the reader’s attention.

Next, we can use headings (<h3> </h3>) to organize the content and provide a clear structure to our answer. Headings help break down the information into smaller sections and make it easier to navigate.

In addition to headings, we can also utilize lists in HTML to neatly present information. Whether it’s an ordered list (<ol> </ol>) or an unordered list (<ul> </ul>), lists help improve readability and make the content more digestible.

Finally, we can emphasize certain words or phrases by using the <b> </b> tags. These tags can be used to make certain parts of the text bold, which can serve to highlight important information or draw attention to key points.

By following these formatting techniques, we can enhance the clarity and structure of our answer, making it more engaging and easier to understand for our audience.
