Khan Academy uses a step-by-step approach to teaching students how to add fractions with unlike denominators. The first step is to find a common denominator for both fractions. This is done by finding the least common multiple (LCM) of the two denominators.Once a common denominator has been found, the next step is to adjust the numerators so that they are equivalent to the original fractions. This is done by multiplying the numerator and denominator of each fraction by the same number. This ensures that the value of the fraction remains the same, but the denominators are now the same.Example 1:
Let's take the example of adding 1/2 + 3/4. The first step is to find the least common multiple of 2 and 4, which is 4. Then we adjust the fractions to have the same denominator: 1/2 = 2/43/4 = 3/4Now we can add the fractions: 2/4 + 3/4 = 5/4Example 2:
Another example would be adding 1/3 + 2/5. The lcm of 3 and 5 is 15. Adjusting the fractions:1/3 = 5/152/5 = 6/15Then we can add them up:5/15 + 6/15 = 11/15Interactive Practice

Fortunately, there are several online resources that can help students learn how to add fractions with unlike denominators. One popular resource is Khan Academy. Let's compare Khan Academy's method for adding fractions with unlike denominators to traditional methods.Basic Concept of Adding Fractions with Unlike Denominators
Before we start comparing the methods to solve adding fractions problems, it's helpful to review the basic concept of adding fractions with different denominators.When we add or subtract fractions with different denominators, we must first find a common denominator. A common denominator is a shared multiple of the two denominators. Once we've identified this number, we rewrite each fraction with this common denominator. Then, we proceed to add (or subtract) the numerators and simplify the result, if possible.Khan Academy Tutorial on Adding Fractions with Unlike Denominators
Let's take a look at how Khan Academy teaches the concept of adding fractions with unlike denominators. According to their tutorial, the first step is to find a common denominator. To find a common denominator, they suggest listing the multiples of each denominator until you find the smallest multiple both denominators have in common. Once you have the common denominator, Khan Academy's method involves breaking each fraction down into smaller, simpler steps, before finally combining them together. Here is an example problem and the steps Khan Academy recommends to add two fractions with different denominators:Problem: $\frac{1}{3} + \frac{1}{4}$ Step 1: Find a common denominator - 12 is a multiple of both 3 and 4 Step 2: Rewrite the fractions with the common denominator (you will need to multiply each fraction by a factor of 1) $\frac{1}{3} \times \frac{4}{4} = \frac{4}{12}$$\frac{1}{4} \times \frac{3}{3} = \frac{3}{12}$Step 3: Add the numerators with the same denominator $\frac{4}{12} + \frac{3}{12} = \frac{7}{12}$Step 4: Simplify the result if possibleThe result $\frac{7}{12}$ is already in its simplest form.Comparison between Khan Academy and Traditional Method
Now that we know how Khan Academy teaches adding fractions with unlike denominators, let's compare this method to traditional methods.One of the traditional methods for adding fractions with unlike denominators involves finding the common denominator first and then adding the numerators together.Using the same problem from before, here are the steps for the traditional method:Problem: $\frac{1}{3} + \frac{1}{4}$Step 1: Find a common denominator - 12 is a multiple of both 3 and 4Step 2: Rewrite the fractions with the common denominator (you will need to multiply each fraction by a factor of 1)$\frac{1}{3} \times \frac{4}{4} = \frac{4}{12}$$\frac{1}{4} \times \frac{3}{3} = \frac{3}{12}$Step 3: Add the numerators with the same denominator$\frac{4}{12} + \frac{3}{12} = \frac{(4+3)}{12} = \frac{7}{12}$Step 4: Simplify the result if possibleThe result $\frac{7}{12}$ is already in its simplest form.Pros and Cons of Khan Academy Method
Now that we've compared the Khan Academy method to traditional methods, let's discuss some pros and cons of their approach.One advantage of Khan Academy's method is that it breaks down the problem into smaller steps, which can be helpful for students who are struggling withe the concept. By showing multiple ways to rewrite each fraction with the common denominator, Khan Academy provides a step-by-step process for students to follow.Additionally, Khan Academy's use of visuals, such as the number line and shading, can be particularly helpful for students who learn better through visual aids.One potential disadvantage of the Khan Academy method is that it may be more time-consuming than traditional methods. By breaking the problem down into simpler parts, students will have to complete more calculations before they can arrive at the final answer.Conclusion
In conclusion, adding fractions with different denominators can be a challenge for students, but there are several resources that can help. While Khan Academy offers a comprehensive tutorial on how to solve these types of problems, there are also traditional methods that work just as well. Ultimately, the key is to find the method that works best for you and your learning style.Adding Fractions With Unlike Denominators Khan Academy
Introduction
Adding fractions with unlike denominators can be a tricky arithmetic exercise. However, it is an essential skill that individuals need to acquire, especially in daily life. Whether it is calculating the amount of ingredients needed in a recipe or processing financial transactions, knowing how to add fractions with unlike denominators is crucial. In this tutorial, we will explore the steps involved in adding fractions with unlike denominators and provide examples for clarity.Step 1: Find a common denominator
The first step in adding fractions with unlike denominators is finding a common denominator. This involves identifying a shared multiple of the two denominators. For instance, if we are adding 1/4 and 1/6, we would choose 12 as our common denominator since both 4 and 6 are factors of 12.Step 2: Convert the existing fractions
After identifying a common denominator, the next step is converting the existing fractions. This new form of the fraction will have the same value but will have the same denominator as the common denominator.To convert the fractions, multiply the numerator and denominator of each fraction with the common denominator. For example, if we are converting 1/4 to 3/12, we multiply both the numerator and denominator by 3.Step 3: Add the converted fractions
Once we have converted the fractions, it's time to add them. Add the numerators of the fractions and write the sum over the common denominator. This gives us the solution to our problem.For instance, continuing with the previous example, adding 3/12 and 2/12 would give us 5/12.Example One
Suppose we have the fractions 1/3 and 2/5. The first step is finding a common denominator, which is 15 since it is a multiple of both 3 and 5. Next, we convert the first fraction to have the same denominator as the second fraction. To do this, we multiply both the numerator and denominator of 1/3 by 5. This gives us 5/15. We can then convert the second fraction to have the same denominator as the first fraction by multiplying both the numerator and denominator by 3. This gives us an equivalent fraction of 6/15. The last step is adding the converted fractions: 5/15 + 6/15 = 11/15. Therefore, 1/3 + 2/5 = 11/15.Example Two
Suppose we have the fractions 1/2 and 3/7. The first step is finding a common denominator, which is 14 since it is a multiple of both 2 and 7. Next, we convert the first fraction to have the same denominator as the second fraction. To do this, we multiply both the numerator and denominator of 1/2 by 7. This gives us 7/14. We can then convert the second fraction to have the same denominator as the first fraction by multiplying both the numerator and denominator by 2. This gives us an equivalent fraction of 6/14. The last step is adding the converted fractions: 7/14 + 6/14 = 13/14. Therefore, 1/2 + 3/7 = 13/14.Conclusion
In conclusion, adding fractions with unlike denominators can be challenging, but with the right approach, it becomes easier. The steps involved include finding a common denominator, converting the existing fractions, and adding the converted fractions. With these steps, individuals can add any fraction with unlike denominators accurately.Adding Fractions With Unlike Denominators Khan Academy
Welcome to Khan Academy's guide to adding fractions with unlike denominators! In this article, we will explain the easiest ways to add fractions with different denominators and help you understand this conceptual topic better. By the end of this article, you will be able to solve challenging questions on adding fractions with unlike denominators without any trouble.
Before diving into the topic, let us take a quick recap on what are fractions, and what are denominators? A fraction is defined as a numerical quantity which is represented by a division between two integers or numbers, one above the line denoting numerator and the other below it denoting the denominator. A denominator is the bottom number of the fraction that represents the total number of equal parts in the whole. It is essential to have the same denominator when adding or subtracting fractions. It helps to retain the accuracy of the result and ensure that we never lose any fractional values along the way.
If the fractions don't have the same denominators, they are called fractions with unlike denominators. So, how do we add such fractions? There are multiple methods of solving this problem, such as the cross-multiplication method and the use of common denominators. However, we will focus on the simplest and most straightforward solution – finding the least common multiple (LCM).
The LCM is a well-known method for finding the lowest common denominator (LCD) easily, which is highly useful for adding and subtracting fractions. To determine the LCM, you need to find the smallest number that both denominators will divide into perfectly. Once you have found it, you need to change both the fractions so that they have the same denominator, i.e., the LCD.
For instance, consider two fractions that we need to add: 1/4 and 2/5. The LCM of 4 and 5 is 20. Thus, we will convert both the fractions to their equivalent form with a denominator of 20. For that, you need to multiply the numerator and denominator of each fraction by the same number required to make the denominator as the LCM, i.e., 20. So, the first fraction will be multiplied by 5/5 and the second fraction by 4/4.
Thus, 1/4 becomes 5/20 (5 x 1 = 5; 4 x 5 = 20), and 2/5 becomes 8/20 (4 x 2 = 8; 5 x 4 = 20). Now, when we add these two fractions, we get 5/20 + 8/20 = 13/20. Thus, the sum of 1/4 and 2/5 is equal to 13/20. Isn't that simple?
In conclusion, adding fractions with unlike denominators is an elementary topic in maths. Yet, it requires patience, attention and accuracy to solve such questions. We hope this article has helped you understand the concept better and equipped you with the skills you need to solve such problems. Remember, practice and persistence are key to mastering any topic. So, keep practicing, and you'll be amazed at how confident you feel when it comes to adding fractions with unlike denominators.
