Understanding Ratios

A ratio is a fundamental  mathematical concept that expresses the relative size of two or more values. It is a comparison that tells us how much of one thing there is compared to another. In the United Kingdom, ratios appear in many aspects of daily life, from the mixing proportions in a classic Victoria sponge recipe to the scale on an Ordnance Survey map used for hiking in the Peak District. They provide a clear and concise way to understand relationships between quantities without needing to know the exact amounts.
