Ratios play a significant role in mathematics, enabling comparison and scaling between different quantities. A ratio is a mathematical expression that represents the relationship between two or more numbers, typically expressed as a simple fraction. It highlights the proportional relationship between the two parts, showcasing the relative size or measure of each.

Ratios are often used in everyday life to compare quantities or measures, such as the ratio of boys to girls in a classroom or the ratio of ingredients in a recipe. In more complex applications, ratios are used in both scientific and financial areas, like fiscal ratios to determine the financial stability of a company or the ratio of pH in chemistry to indicate the acidity or basicity of a substance.

To form a ratio, two numbers are chosen, often referred to as the 'ante' and the 'corps', and these are compared to a base unit. This base unit allows further processing, such as in fractions where the ratio between the numerator and the denominator is evaluated. Ratios can also be used in reverse, returning the value into the original equation.

In addition, ratio tests are used in series to determine the convergence or divergence of the series. This method evaluates whether the terms of the series decrease fast enough for it to converge to zero. Other examples of ratio applications include the calculation of the cross-ration to build a gaging point or ratios of increased performance over a certain distance when organizing compensations.

Further development of ratio techniques can be found in probability theory as the ratio locked in sequence to deliver pseudorandom numbers.
