60-second Quick Read
- Financial models can compare income tax, pay rates and phone plans using formulas and break-even reasoning.
- Radiocarbon dating ratios use repeated halving; 25% remaining means two half-lives.
- Common trap: Ratios must include clear units, especially in cordage, fibre and length-to-mass contexts.
