Fractions

Break them down

Multiply that

Fractions

Break them down

And divide that

Fractions

Break them down

And subtract that

Fractions

Break them down

You know you’ve got to add that

Numbers over numbers got to break it down (break it down)

Greatest common factor then I take it down (take it down)

Numbers on the bottom (yea them numbers on the bottom)

First I spot them then I got them

Got to make them the same

but only if I want to add that

but if i aint trying to have that

probably mean that I’m gonna multiply

it’s an easy reason to laugh at

first the top two then the bottom til you get it

but you know that we aint fininshed (uh uh)

come on and get with it

cause everyone knows sometimes you’ve got to simply

so I want to explain how to identify

numerator, denominator divided by the same thing

do it til you can’t no more the answer’s there it’s waiting

Now all this fractions business is a breeze

Success so typical they kind of freeze (they kind of freeze)

No rats or mice but you know we getting cheese (we getting cheese)

And you know it’s cause we do it all with these (okay)

Fractions

Break them down

Multiply that

Fractions

Break them down

And divide that

Fractions

Break them down

And subtract that

Fractions

Break them down

You know you’ve got to add that

And we’re talking division

Listen up don’t miss this

There’s a process

Taking a second to see if I got ya’ll attention

Second fraction, I flip it

Call that the reciprocal

Get that I’m good to go

Good to roll I’m in the flow

The way I do it’s so beautiful

Then I’m back to multiplication (yea)

Top and then the bottom, right

Yea, I’m listening to my training

If they’re hot, then we’re flaming

Cause we get it right and that’s every time (yea)

Kind of like it’s every time I bust a rhyme and it’s always fly (right)

You know we’re talking about them fractions (fractions)

Get the answer to the question then I am relaxing (relaxing)

Want to know the known parallel then I’m taxing (taxing)

Piece of the pie man you know I’m about my fractions (fractions)

Ha, and now we’re living like we’re supposed to be

Hear the right answer in the class then you know it’s me

(right) know it’s me, you know it’s me

And you know we rolling deep

And you know it’s KMG

And now you know about fractions

Get a pencil and work until 3

Fractions

Break them down

Multiply that

Fractions

Break them down

And divide that

Fractions

Break them down

And subtract that

Fractions

Break them down

You know you’ve got to add that

Greatest common factor-GCF

Least common denominator-LCD

Add up fractions with different (different) different (different) denominators

Find the LCD

Rename the fractions to have the LCD

Add numerators of the fraction

And simplify that fraction (that fraction)

2 over 9 3 over 12 the GCD is 3 (3)

Cause 3 goes into 9 and 12 (3 goes into 9 and 12)

Divide one and multiply the other by 3 (3) 3 (3)

Watch me break down these fractions then eat (eat) see

Rename the fractions and use the LCD (D) D

2 (2) over 9 is now 8 (8) over 36

3 over 12 turns to 9 over that LCD

The way I’m working through these fractions

You’ve got nothing on me

Then you add the numerators over that LCD

So, the answer is 17 over 36 you see

That’s how you break down these fractions so eat (eat) see

Fractions

Break them down

Multiply that

Fractions

Break them down

And divide that

Fractions

Break them down

And subtract that

Fractions

Break them down

You know you’ve got to add that
