How ratios are calculated
A ratio shows the relative size of two or more values. The calculator performs two main functions:
- **Simplification:** Dividing all parts of the ratio by their greatest common divisor (GCD) to find the smallest integer representation. E.g. \(15:25 \Rightarrow 3:5\).
- **Scaling:** Solving proportion relations \(A/B = C/D\). If A, B, and C are known, D can be solved using cross-multiplication: \(D = (B \times C) / A\).
