Explanation of P by Q is equals to all by S is equals to pi minus or by Q minus is the process is called

Definition: The given expression states that the ratio of P to Q is equal to the ratio of all to S, which is equal to the ratio of pi minus or to Q minus. This is known as the process of proportionality.

Understanding: Proportionality is a mathematical concept that is used to express the relationship between two or more quantities. In simple terms, it means that two things are equal in proportion. For example, if we say that the ratio of the length of the side of a square to its perimeter is 1:4, then we can say that the length of the side is 1/4th of the perimeter.

Example: Let us understand the given expression by taking an example. Suppose P= 2, Q= 4, all= 6, S= 12, pi minus or= 3 and Q minus= 2.

- P by Q= 2/4= 1/2
- All by S= 6/12= 1/2
- pi minus or by Q minus= 3/2

We can see that all the ratios are equal to 1/2, which is the same as P by Q.

Conclusion: The given expression is used to express proportionality between quantities. It is a mathematical concept that is used in various fields, such as physics, engineering, finance, and more. Understanding the concept of proportionality is essential in solving various mathematical problems.
