I have a common denominator.

Our common denominator is 12.

We have a common denominator now, 3.

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.

Well, the common denominator is 13 times 12.

The common denominator here is 13 times 12.

So now we have a common denominator here.

So that's going to be our common denominator

And if we want to add them up, if we want to find a common denominator (The common denominator is 100.)

I have found a common multiple it is the smallest multiple they have other common multiples like 48,72 and we can go on but this is their smallest common multiple

They found a common denominator and all the rest.

And that common denominator used to be the least common multiple of eleven and thirteen

You can't run a society by the lowest common denominator.

And the common denominator is going to be the least common multiple of 12 and 13.

So, the trick here is to first find the common denominator.

So what we want to do is write a common denominator.

And now I have to worry about finding a common denominator.

So now I have to worry about finding a common denominator.

So let's write all of them with 300 as the common denominator.

And I wrote it that way so I have a common denominator.

So I'm saying the common denominator here is going to be 252.

And then I added this to this, I got a common denominator.

So, we've rewritten each of these fractions with the new common denominator.

And to add two fractions, you have to have a common denominator.

13 6, and this is equal to once again we're going to get the common denominator over here and it looks like 24 will be the common denominator.

That's the same thing as, we have to find the common denominator here, the common denominator, or the least common multiple of 4 and 8 is 8, so it's going to be something over 8.

See, if I were to have a common denominator I'm just doing a

We have to rewrite the following fractions with fraction with least common denominator

And regardless of whether it's nuclear reactors or metamaterials or whale sex, the common or lowest common denominator is me.

Smallest

So here, just like there, the numerator and the denominator have a common factor.

Six ninths minus two fifths. Well we're gonna have to find a common denominator.

And so my TED wish is based on the common denominator of these experiences.

And we already have a common denominator, so we can just add the fractions.

In order to add these two fractions we need to find a common denominator

And that is going to be equal to let's get a common denominator, 144.

The common denominator of 3 4 and 2 3 is going to be the least common multiple of 4 and 3.

And to figure out the common denominator, you just have to think about the least common multiple of 10 and 100.

In this particular example, the third smallest, here's the smallest, here's the second smallest, and here's the third smallest.

So this is definitely a common multiple and it is the smallest of all of their LCMs.

Smallest coin

And in order to be able to do this, we need to find a common denominator.

Now if we want to actually add these as fractions we could have a common denominator.

And, the easiest way and the way that people are sure to get the right answer is to find a common denominator, because if we can't find a common denominator, these fractions are difficult to compare

So the smallest LCM... ...so if we only cared about the least common multiple of 15 and 6.
