Lyrics:

Let me tell you about a word,
That starts with letter D,
Denominator,
Is that word,
Check it out, you'll see...
D is for denominator,
D is also for down,
D is starting off both words,
With the same D sound...

It's the 2 in 1/2,
The 3 in 2/3,
The 4 in 1/4,
The D's for this word...
It's the 2 in 1/2,
It's the 3 in 2/3,
It's the 4 in 1/4,
Don't stop (OK)
It's the 5 in 4/5,
The 6 in 3/6,
And in fractions it's never the top!

D is for down now,
Take me to the action...
D is for down now,
Bottom of a fraction...

Let me tell you about a word,
That starts with letter D,
Denominator is that word,
Check it out you'll see...
D is for denominator,
Starts with letter D,
Just like D in down down down,
To the bottom of the sea...

It's the 8 in 4/8,
The 3 in 4/3,
The 9 in 8/9,
The D's for this word...
It's the 8 in 4/8,
The 3 in 4/3,
It's the 9 in 8/9,
Don't stop! (OK)
It's the 12 in 2/12,
The 6 in 4/6,
And in fractions it's never the top!

D is for down now,
Take me to the action...
D is for down now,
Bottom of a fraction...

Let me tell you about a word,
That starts with letter D,
Denominator is that word,
Check it out you'll see...
Denominator-elevator,
Starts off on the ground,
Only has one button now,
D for going down!

It's the 10 in 5/10,
The 3 in 10/3,
The 8 in 9/8,
The D's for this word...
It's the 10 in 5/10,
It's the 3 in 10/3,
It's the 8 in 9/8,
Don't stop (OK)
It's the 2 in 12/2,
The 6 in 5/6
And in fractions it's never the top!

Let me tell you bout a word,
That starts with letter D,
Denominator,
Is that word,
Check it out, you'll see...
D is for denominator,
D is also for Down,
Not an N for numerator,
Nap, no, night, nor Noun...

D is for denominator,
Denominator's always down,
D is for down down down,
Denominator's always down,
D is for down down down,
Denominator's always down!
