Introduction

Mathematics is one of the essential skills that every student should have. It's a fundamental subject that lays the foundation for future studies. Still, many students find it challenging, especially when it comes to fractions. Fractions involve numerous concepts such as adding, subtracting, multiplying, and dividing with fractions. This article focuses on adding fractions with unlike denominators, a concept that most students find daunting, but thanks to Khan Academy, the topic has been made user friendly and easy to understand.

The Basics of Adding Fractions with Unlike Denominators

Adding fractions with unlike denominators requires finding the common denominator. This term refers to a fraction in which both fractions can be converted to look the same. Once this is done, it's now easy to add the fractions. However, finding the common denominator can be a tricky affair, especially for students who are not familiar with the concept. For this reason, the introduction of online resources, such as Khan Academy, provides an excellent platform to help students learn this concept with ease.

Comparison: Khan Academy vs. Traditional Method of Adding Fractions with Unlike Denominators

Introduction

Khan Academy is an online learning platform offering free video tutorials on various subjects, including mathematics. One of the topics covered by the site is the addition of fractions with unlike denominators. In this article, we will compare the Khan Academy method with the traditional method of adding fractions with unlike denominators.

The Khan Academy Method

The Khan Academy method of adding fractions with unlike denominators involves several steps. First, the learner must find the least common multiple (LCM) of the denominators. Then, they must convert each fraction so that its denominator is the LCM. Finally, they can add the numerators and simplify the answer, if necessary.

Step 1: Find the LCM of the Denominators

The LCM is the smallest multiple that two or more numbers have in common. For example, the LCM of 2 and 3 is 6. To find the LCM of the denominators in a fraction problem, the learner must list the multiples of each denominator until they find a number that is common to all of them. For example, the LCM of 2, 3, and 4 is 12, since 12 is a multiple of all three numbers.

Step 2: Convert Each Fraction

Once the LCM is found, the learner must convert each fraction so that it has the same denominator as the LCM. To do this, they must multiply the numerator and denominator of each fraction by a factor that will make the denominator equal to the LCM. For example, if the fractions are 1/2 and 2/3, and the LCM is 6, the learner would convert 1/2 to 3/6 and 2/3 to 4/6.

Step 3: Add the Numerators and Simplify

After converting each fraction, the learner can add the numerators and simplify the fraction, if necessary. To simplify a fraction, the learner must find the greatest common factor (GCF) of the numerator and denominator and divide both by it. For example, if the answer is 10/12, the learner would divide both the numerator and the denominator by 2 to get 5/6.

The Traditional Method

The traditional method of adding fractions with unlike denominators is to find a common denominator by multiplying the denominators together. Then, the learner must convert each fraction so that it has the same denominator as the common denominator. Finally, they can add the numerators and simplify the answer, if necessary.

Step 1: Find the Common Denominator

The common denominator is found by multiplying the two denominators together. For example, if the fractions are 1/2 and 2/3, the common denominator is 6 (2 x 3).

Step 2: Convert Each Fraction

Once the common denominator is found, the learner must convert each fraction so that it has the same denominator as the common denominator. To do this, they must multiply the numerator and denominator of each fraction by a factor that will make the denominator equal to the common denominator. For example, if the original fractions are 1/2 and 2/3, the learner would convert 1/2 to 3/6 and 2/3 to 4/6.

Step 3: Add the Numerators and Simplify

After converting each fraction, the learner can add the numerators and simplify the fraction, if necessary. To simplify a fraction, the learner must find the greatest common factor (GCF) of the numerator and denominator and divide both by it. For example, if the answer is 10/12, the learner would divide both the numerator and the denominator by 2 to get 5/6.

Comparison Table

Steps	Khan Academy Method	Traditional Method
Step 1	Find the LCM of the denominators	Find the common denominator by multiplying the denominators together
Step 2	Convert each fraction to have the same denominator as the LCM	Convert each fraction to have the same denominator as the common denominator
Step 3	Add the numerators and simplify	Add the numerators and simplify

Opinion

Both the Khan Academy method and the traditional method of adding fractions with unlike denominators are effective ways to solve this type of problem. However, the Khan Academy method may be easier for some learners to understand and remember, as it involves finding the least common multiple instead of multiplying the denominators together. Additionally, the Khan Academy method may be more versatile, as it can be used for more complex math problems that involve more than two fractions. Overall, the Khan Academy method is a great resource for those looking to improve their math skills, and it offers an alternative approach to traditional methods of problem-solving.

Khan Academy: Adding Fractions With Unlike Denominators

Are you struggling with adding fractions that have different denominators? Don't worry, you're not alone! This can be a tough concept to grasp, but with the help of Khan Academy, you'll be able to master it in no time. In this blog post, we'll walk you through the steps and strategies for adding fractions with unlike denominators.

But before we dive into the nitty-gritty, let's review some basics. A fraction is made up of a numerator and a denominator. The denominator represents the total number of equal parts in a whole, while the numerator represents how many of those parts are being counted. When adding fractions, the denominators must be the same in order to combine the numerators.

So, what do you do when you're faced with fractions that don't have the same denominators? That's where finding a common denominator comes in. A common denominator is a multiple of both denominators that allows the fractions to be added or subtracted. Let's take a look at an example:

2/3 + 1/4 = ?

The first step is to find a common denominator. One way to do this is by multiplying the denominators together:

3 x 4 = 12

Now, we need to turn each fraction into an equivalent fraction with the new denominator of 12. This is done by multiplying the numerator and denominator by the same number.

So, for 2/3:

(2/3) x (4/4) = 8/12

And for 1/4:

(1/4) x (3/3) = 3/12

Now that we have common denominators, we can add the numerators:

8/12 + 3/12 = 11/12

So the answer is 11/12.

While this process may seem daunting at first, it becomes easier with practice. Khan Academy offers a variety of resources to help you master adding fractions with unlike denominators.

The first step is to watch their video lesson on Adding Fractions With Unlike Denominators. This video breaks down the steps and gives examples for adding fractions of all different kinds.

Next, try out their interactive exercises on adding fractions with unlike denominators. These exercises will give you the opportunity to practice what you've learned and get immediate feedback on your answers.
