What are proportions?
Answer (2)
A proportion is an equation which states that two ratios are equal.
For example, b a = d c is an example of a proportion. In the given proportion, a and d are called extremes and b and c are called means. The first property that I will talk about states that the product of the extremes equals the product of the means. This idea is called the (means-extreme property).
Proportions describe the equality of two ratios or fractions, represented as b a = d c . They can be directly proportional, where one quantity changes with another, or inversely proportional, where one quantity changes opposite to another. Understanding proportions helps in many practical applications like cooking and understanding maps.
