Practical Use Cases for Ratio Simplifier
Aspect Ratio Simplification for Video & Photography
Simplify display resolutions (e.g. $2560:1440 \rightarrow 16:9$, $3840:2160 \rightarrow 16:9$) to identify standard video aspect ratios.
Chemical Solution & Mixing Ratios
Simplify concrete mixtures, paint blends, and resin formulas (e.g. $150\text{ml} : 75\text{ml} : 25\text{ml} \rightarrow 6:3:1$).

Key Terminology & Definitions
Ratio
A mathematical comparison showing how many times one number contains another ($A:B = A/B$).
Unit Ratio
A ratio where one of the terms is scaled to 1 (e.g. $16:9$ expressed as $1.78 : 1$), widely used in widescreen displays.
