What is constant ratio in maths?

In mathematics, a constant ratio refers to a fixed relationship between two quantities where their proportional relationship remains unchanged. For example, if two quantities ( A ) and ( B ) have a constant ratio of ( k ), it can be expressed as ( \frac{A}{B} = k ). This concept is often used in proportions and similar figures, indicating that as one quantity changes, the other changes at a consistent rate. Constant ratiOS are essential in various mathematical applications, including scaling and comparisons.
