The componendo and dividendo rule are used while studying ratios and proportions. If the ratio of any two given numbers is the same as the ratio of the other 2 numbers, then the ratios of the sum total of the numerator and denominator to the difference of the numerator and denominator of the two rational numbers are equal in nature. Componendo and dividendo is a theorem on proportions that allows for a quick way to perform calculations and reduce the amount of expansions needed. It is particularly useful when dealing with equations involving fractions or rational functions in mathematical Olympiads, especially when you see fractions of the following form:
Componendo dividendo How It Works and How It Is Used
Componendo and dividendo is a theorem on proportions that allows for a quick way to perform calculations and reduce the number of expansions needed. It is particularly useful when dealing with equations involving fractions or rational functions in mathematical Olympiads, especially when you see fractions. Componendo and Dividendo are generally used where the ratio or proportion involves fractions or rational functions to simplify the equations and make calculations easier. Other than Componendo and Dividendo there are two more similar rules algebra i.e., Alternendo and Invertendo. Understanding the Componendo-Dividendo rule: A key theorem in the study of proportions offers a quicker method for performing calculations and reduces the number of expansions needed. This rule proves particularly useful when dealing with equations involving fractions or rational functions. Componendo dividendo is a proportion based 3 step quick method of simplifying the relation between the quantities in a given proportion (like a: b = c: d a: b = c: d, where ratio a: b a: b is proportional to the second ratio c: d c: d with constant of proportion 1). It minimizes the steps otherwise needed.

Componendo and Dividendo Formula simplifies or transforms equations by adding or subtracting the numerator and denominator of two fractions. In this article, we will explain the Matric Math concept: what componendo and dividendo are, how to use them, and why they are useful in trigonometry, specifically. What are Componendo and Dividendo? Componendo and Dividendo Rule Math Doubts Basics Formula a b = c d ⇔ a + b a − b = c + d c − d Proof a, b, c and d are four literals but b and d are non-zero literal numbers. Assume, the ratio of a to b is equal to the ratio of c to d. a b = c d Step: 1 Add one both sides of the left and right hand side fractions. a b + 1 = c d + 1 Componendo-Dividendo Duplicate Ratios Variations Ratios and Proportion Practice Questions Componendo In Componendo the basic rule that you need to remember is if a : b : : c : d than (a + b) : b : : (c + d) : d. Thus, in Componendo as you can see that you need to add the denominator to numerator given in the ratios and then equate them. Can we apply the Componendo and Dividendo from Algebra as given below?: A + B A − B = C + D C − D Why do I think "no"? Since A, B, C, and D are of different dimensions, and we know that only quantities of same dimensions must be added or subtracted, we must not apply the Componendo and Dividendo.

Some useful properties of ratio and proportion are invertendo property, alternendo property, componendo Property, dividendo property, convertendo property, componendo-dividendo property, addendo property and equivalent ratio property. These properties are explained below with examples.
How to Solve Componendo Dividendo Questions on Algebra Quickly
When componendo dividendo is applied on $\displaystyle\frac{b+a}{b-a}$ resultant ratio will be $\displaystyle\frac{b}{a}$. Rule: By simple componendo dividendo, numerator of resultant ratio will be the variable that is positive in both numerator and denominator. Solution Step I: Definition of componendo and dividendo. Componendo and dividendo is a rule on ratio and proportions that is used to perform calculations and reduce the number of steps. This rule is generally used to solve equations and fractions. Step II: Componendo and Dividendo Rule.
