Denumerator

So now, this is looking pretty similar.

We actually take the denominator, we say how many times does it go into the numerator?

And then our denomenator is going to be

Because when you multiply fractions, you just multiply the numerator times the numerator divided by the denominator times the denominator.

And then we also, in the denominator, right over here, we also, right over here in the denominator have seconds.

The denominator, we know what the denominator is, it is x to the fourth plus 27 squared.

We're multiplying it by 100 in the denominator.

They're the same denominator.

That is our denominator.

That's going to be the denominator.

The four is the denominator.

What is the denominator going to be equal to?

This would have been a 2.

And then in the denominator

We keep the denominator the same.

All that over eighteen.

And this'll be the denominator.

In the first place...

So the same numerator, the larger the denominator, the smaller the quantity is going to be.

To the minus 2, you just put in the denominator and make it into a positive 2 in the denominator.

In this video, we're going to learn how to rationalize the denominator.

And I wanted to write that with the denominator let's say I wanted to write that with the denominator 36.

In the denominator, we just have a 6y.

Let me write the denominator here

It will make our denominator 0.

We take a common denominator. So 6 is the same thing as

And then they want us to find the denominator.

So what is our denominator going to be equal to?

That'll be our new denominator.

And I'll start off by trying to simplify this denominator here.

And in the denominator what happens?

And now we have the same denominator.

That's the denominator there, 2.

The common denominator is two

You do the denominator.

The numerator divided by the denominator.

Well, we just keep the denominator the same.

And of course, we keep the denominator the same.

The numerator is larger than the denominator.

When you add anything, you find the common denominator, and the common denominator, the easiest common denominator, is to multiply the two denominators, so let me write this here.

If we have the same denominator, the denominator in the difference is going to be the same as the denominators in the two numbers that we're subtracting, so it's going to be 18.

And now we have to make all three of these characters have the same denominator and that denominator has to be the

When you multiply fractions, it's just the numerator times the numerator, over the denominator times the denominator.

Above all, these are
