Ratio It is a Latin word recognized by the Royal Spanish Academy which is used as a synonym for reason , in the sense of quotient of numbers or comparable quantities .
The arithmetic reason It is the constant difference between two consecutive terms of an arithmetic progression. The geometric reason , on the other hand, is the constant quotient between two consecutive terms of a progression geometric.
A ratio, in short, is the ratio or ratio of two interrelated magnitudes . The financial or accounting ratios are the coefficients that provide financial units of measurement and comparison. Through them, the relationship presented by two financial data is established and it is possible to analyze the status of a organization based on their optimal levels.
For the comparison of the data to be consistent, they must correspond to the same period of time. On the other hand, the data to be verified must maintain a financial relationship, economical and administrative.
Financial ratios allow you to measure the liquidity, profitability and solvency of the Business. There are also activity ratios , productivity ratios and balance ratios , among others.
The concept of ratio is also used in the computing . Programs that allow you to share files from person to person (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 that file; on the other hand, it is called sharing ratio to the ratio of uploading and downloading of information from a user (if a user uploaded 600MB of data to a system and downloaded 300MB, its sharing ratio is 2.0).
Aspect ratio
At present, with the growing success of the TV in high definition, with its 3D variant and the presentation in society of the first screens with 4k resolution (about four times more than the current 1080p standard) and the promise of a future in 8k, the concept of aspect ratio (translated as aspect ratio) is increasingly known to 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 adjust the image.
The aspect ratio of a painting is nothing other than the proportion between its dimensions horizontal and vertical, 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 found four types Aspect ratios: 16:9, 16:10, 3:2 and 4:3, each associated to 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 amount of pixels that a screen is capable of displaying simultaneously; in the same way, 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 give their users the possibility of altering the aspect ratio to correctly visualize the content, most viewers do not seem to notice when one or the other corresponds, and usually use 16: 9 as standard.
Although there is an option generally called "automatic width", which promises to make the necessary adjustments without the need for any intervention by the user, the results are not always as expected, not to mention that this does not work in the same way worldwide.
