(Verse 1)
Fractions can be tricky, it's true,
When denominators aren't the same for you.
But don't you worry, don't you fret,
A simple method, we'll learn it yet!
(Chorus)
First step, first step, what do we seek?
A **common denominator**, that's what we speak!
Look for the **LCM**, the least of the lot,
The smallest number both bottoms have got!
(Verse 2)
Let's say you've got 1 over 3 and 1 over 4, you see,
The denominators are 3 and 4, for you and me.
To find the **LCM**, let's list them with care,
Multiples of 3: 3, 6, 9, **12**, right there!
Multiples of 4: 4, 8, **12**, what a find!
Our **LCM** is 12, leaving no number behind!
(Chorus)
First step, first step, what do we seek?
A **common denominator**, that's what we speak!
Look for the **LCM**, the least of the lot,
The smallest number both bottoms have got!
(Verse 3)
Now change your fractions, keep their value true,
Multiply top and bottom, the same for both of you.
For 1 over 3, to get to 12 below,
Multiply by 4, and watch that fraction grow!
So 1 over 3 becomes 4 over 12 yes it's true,
And for 1 over 4, multiply by 3, me and you!
So 1 over 4 becomes 3 over 12, what a sight,
New fractions ready, all shiny and bright!
(Chorus)
First step, first step, what do we seek?
A **common denominator**, that's what we speak!
Look for the **LCM**, the least of the lot,
The smallest number both bottoms have got!
(Verse 4)
Now the bottoms match, it's plain to see,
Time to **add the numerators**, happily!
4/12 plus 3 over 12, just add the tops,
Four plus three makes seven, and the adding stops!
So our answer, with a cheer and a shout,
Is 7 over 12, without a doubt!
(Outro)
So next time you're faced with fractions to sum,
Remember these steps, and the answer will come!
Find the **LCM**, change the tops too,
Then add them together, for me and for you!
