What Is the Difference Between Ratio and Proportion?

A ratio is a representation in mathematics of the connection that exists between two entities, most often quantities, whereas a percentage is a reference to the equivalence of two ratios that have been presented. In most contexts, a ratio is nothing more than an expression, while a percentage may be expressed in the form of an equation.

The outcome of expressing two quantities in the form of a ratio, which uses the same units for both, is an abstract number that can be calculated by dividing one item by the other. You may write a ratio either in fractional form or by using the sign “:” instead. It is not possible to use a ratio to express a relationship between quantities that have different unit systems. In mathematics issues involving proportions that are represented in fractions, it is possible to answer a problem with a missing value if all of the other terms have been supplied.
