### Equivalent Fractions

#### Lesson Objective

In this lesson, we will learn the important ideas behind equivalent fractions and how to find these fractions.

#### About This Lesson

One of the most important thing that we need to know when learning fractions is to be able to find fractions that are equivalent.

A good understanding in this will help you to solve problems that involve fractions with different denominators.

You can proceed by reading the study tips first or watch the math video. You can try out the practice questions after that.

### Study Tips

#### Tip #1

Two fractions are considered equivalent when they have the same value. See the picture below:

#### Tip #2

Now, we can find equivalent fractions using the following steps:

- Multiply/divide the numerator with a number
- Multiply/divide the denominator with the same number

Below are some examples to illustrate this:

Using Multiplication

Using Division

In this lesson, we will learn about equivalent fraction. We will also learn how to find them.

00:00:09.010

Let's start. Equivalent fractions are fractions that have the same value. What does this means? Let's find out.

00:00:18.040

Consider this fraction, 1/2. We know that this fraction is the same as 1 divides 2, which is equals to 0.5.

00:00:28.150

Again, let's consider this fraction 3/6. This fraction is the same as 3 divides 6, which is also equals to 0.5.

00:00:39.140

Notice that, these 2 numbers are the same.

00:00:44.030

So, this means that these 2 fractions are equivalent.

00:00:49.130

Now, with this in mind, let's examine this visually to understand this better.

00:00:56.230

We are going to use these 2 fractions, 3/4, to further elaborate on this.

00:01:04.140

Let's start finding fractions that are equivalent to 3/4.

00:01:09.120

To find these fraction, we just need to multiply the fraction's numerator, and denominator with the same number.

00:01:17.210

For example, we can multiply the numerator 3, with 2, and the denominator 4, with 2.

00:01:24.230

This gives the fraction 6/8. Now, we can visually see that 6/8, is equivalent to 3/4, because the total height of the colored parts remains the same.

00:01:40.000

Next, let's multiply the numerator 6, with 3, and the denominator 8, with 3.

00:01:47.160

Now, this fraction becomes, 18/24. Again, since the total height of the colored parts are the same, these 2 fractions are equivalent.

00:02:01.070

Now, why do we need to multiply both the numerator and denominator with the same number?

00:02:08.030

In order to explain this, lets say that we only multiply the denominator with 2. This gives 3/8.

00:02:17.050

Here, we can easily see that these 2 fractions are not equivalent. This is because the total height of the colored parts are not the same.

00:02:27.210

Hence, to make them the same again, we need to multiply the numerator with the same number, which is 2 for this case.

00:02:36.090

This gives 6/8, and now these fractions are equivalent again. With this, we can say that equivalent fractions can only be obtained by multiplying the numerator and denominator with the same number.

00:02:51.130

Next, can we also get E.F from division?

00:02:56.110

Let's find out, using this fraction 18/24. Notice that, we can divide the numerator with 6, and denominator with 6.

00:03:08.170

By doing so, we have the fraction, 3/4. Since the total height of the colored parts remains the same, these 2 fractions are equivalent.

00:03:20.230

Here, note that this fraction is a simplified fraction. This is because we are not able to continue to do any more division on it.

00:03:30.080

Now, how about addition or subtraction?

00:03:35.120

Let's find out, by adding 2 to the numerator and denominator. After doing so, we can see that the total heights of the colored parts are not the same.

00:03:48.070

So, addition does not gives E.F.

00:03:55.220

Next, by subtracting the numerator and denominator with 2, again we can see that the total heights of the colored parts are not the same. So, subtraction does not gives E.F.

00:04:10.080

Therefore, we know that, we can get equivalent fractions from multiplication or division, and not from addition or subtraction.

00:04:18.090

That is all for this lesson. Try out the practice question to test your understanding.
