View: Lyric Explanation

Can we be proportional?
Ratios and fractions that are equal, and then
We solve for X or solve for Y
2 over 10 equals X over 5
Then we cross multiply and divide

Chorus:
Line up the same units
The one’s you’re putting on the top
Have got to match the one’s
On the side or the bottom
Line up the same units
And go little over big
Equals little over big
Yea, ya gotta
Gotta cross multiply and divide
A different scale just means a different size
With the same, same proportions

Can we be proportional?
If we need 5 bucks for 7 meals
Bam, two more hungry people show up, so
How much for 9?
Here comes the cross multiply and divide
5 over 7 equals Z over 9

I am a small triangle
You are a large triangle
Yea, our scale can change
Proportions, stay the same
Just take your similar side
And match it up with one of mine

Scale can be proportional
Here’s a box 20 feet long and 7 feet wide
Now, we match up the similar sides
To derive the length of
A smaller version, 5 inches wide
7 over 20 equals 5 over Y
