# Why use componento?

Componendo and divido is a theorem about proportions that allows **A way to perform computations quickly and reduce the number of expansions required**. It is especially useful when dealing with equations in Mathematical Olympiad involving fractions or rational functions, especially when you see fractions.

## How to use Componento?

In componento, we add **denominator to numerator** In dividends, we subtract the denominator from the numerator.

…

- Componedo (a+b)/b = (c+d)/d.
- Dividend: (ab)/b = (cd)/d.
- For k not equal to (a/b), (a+kb)/(a-kb)=. (c+kd)/(c-kd).
- And for k not equal to (-b/d), (a/b) = (a+kc)/(b+kd).

## What are weights and dividends O?

There is another law to use both componendo and dividends. In this law, if a : b : : c : d is greater than (a + b) : (a – b) : : (c + d) : (c – d). So when used together, you have to apply the component in the numerator and the dividend in the numerator.

## What does dividend mean?

## What is an Addendo process?

If ab = cd, then, **ab = cd = a+cb+d** An additional property called scale. Proof: Here, ab = cd. By alternation, we get, ac = bd.

## What is the Componento formula?

Therefore, show that if the ratio of a to b is equal to the ratio of c to d, then **The ratio of a + b to a – b is equal to the ratio of c + d to c – d**. This property is called Combination and Dividend Rules.

## What are the four properties of proportion?

**the nature of proportions**

- (i) If the ratio of the first two quantities is equal to the ratio of the last two quantities, i.e. a : b : : c : d and read ‘a, then the numbers a, b, c and d are proportional to b as c is d’. …
- (ii) Each quantity in a proportion is called its term or proportion.

## What is the 3 b 3 formula?

The a3 – b3 formula is also known as one of the important algebraic identities. It is read as a cube minus b cube.Its a3 – b3 formula is expressed as**3 – b3 = (a – b) (a2 + ab + b2)**.

## What is alternation?

Alternendo property: For four numbers a, b, c, d if a : b = c : d, then **One: c = b:** d; That is, if the second and third terms are swapped, then the four terms are also proportional.

## When can we say that the proportions are inversely proportional?

inverse proportion **When one value increases and the other decreases**. For example, more workers will reduce the time to complete tasks. They are inversely proportional.

## What is a³ B³?

Difference of two squares: a² – b² = (a+ b)(a – b) Sum of two cubes: a³ + b³ = (**A sort of** + b)(a² – ab + b²) The difference between two cubes: a³ – b³ = (a – b)(a² + ab + b²) Remembering these formulas will help you solve quadratic equations quickly. …

## What is the formula for a³ B³?
