Fair settlement is a ratio problem

🔬 This lab is being built

When it opens, it will follow the same flow as every MathIsland lab:

1. 1An opening question — the problem this concept solves
2. 2Why it was needed — where the old tools failed
3. 3Hands-on experiment — sliders, simulations, direct play
4. 4Common misconceptions, broken
5. 5The idea, written as mathematics
6. 6Where you meet it in real life
7. 7Connections to the previous and next concepts
