Ratio is a Latin word recognized by the Royal Spanish Academy that is used as a synonym for ratio , in the sense of the quotient of numbers or comparable quantities .

The arithmetic ratio is the constant difference between two consecutive terms of an arithmetic progression. The geometric ratio , on the other hand, is the constant quotient between two consecutive terms of a geometric progression.

Financial ratios

A ratio, in short, is the ratio or quotient of two magnitudes related to each other . Financial or accounting ratios are the coefficients that provide financial units of measurement and comparison. Through them, the relationship between two financial data is established and it is possible to analyze the state of an organization based on its optimal levels.

For the comparison of data to be coherent, it must correspond to the same period of time. On the other hand, the data to be compared must maintain a financial, economic and administrative relationship.

Financial ratios allow measuring the liquidity, profitability and solvency of companies . There are also activity ratios , productivity ratios and balance ratios , among others.

Relationship

The idea of ​​aspect ratio refers to the proportion between the vertical and horizontal dimensions.

The term in computing

The concept of ratio is also used in computing . Programs that allow person-to-person file sharing ( P2P ) establish two types of ratio: one that indicates the relationship between the number of users who own and share a complete file and the number of users who are downloading said file.

On the other hand, the sharing ratio is the ratio of uploading and downloading information of a user (if a user uploaded 600MB of data to a system and downloaded 300MB, their sharing ratio is 2.0).

aspect ratio

Currently, with the growing success of high definition television , with its 3D variant and the launch of screens with 4K resolution (around four times more than the 1080p standard) plus the advance of 8K, the The concept of aspect ratio is increasingly known by consumers, although very few people seem to understand it in practice, and they end up watching their favorite program stretched or compressed, instead of taking the few seconds required to watch it. image adjustment.

The aspect ratio of a painting is nothing more than the proportion between its horizontal and vertical dimensions , which is obtained by performing a simple division (width / height) and is usually expressed by the formula x:y . In the case of traditional televisions, for example, their aspect ratio is 4:3, which can also be stated as 1.33:1.

Fundamentally, we find four types of aspect ratios: 16:9 , 16:10 , 3:2 and 4:3 , each associated with a different device or platform. It is worth mentioning that these values ​​do not refer to the resolution of a monitor, which simply reflects the number of pixels that a screen is capable of displaying simultaneously; Likewise, depending on the way in which the resolution is expressed, it may or may not give clues about the aspect ratio.

Although for several years now televisions have given their users the possibility of altering the aspect ratio to correctly display the content , most viewers do not seem to notice when one or the other corresponds, and they usually use 16:9 as the standard.

Although there is an option generally called "auto width", which promises to make the necessary adjustments without the need for any intervention on the part of the user , the results are not always as expected, not to mention that this does not work in the same way in everyone.
