## What Does proportional Mean

The Latin term proportionalis came to our language as proportional . This adjective refers to what is linked to a proportion (that is, to the balance or correspondence that is recorded between the components of a whole). It is known as proportionality, on the other hand, to the existing proportion between the parts of the whole or between the parts and the whole.

For example: "The increase in wages must be, at least, proportional to the increase in the cost of living" , "In this business, each one will take a proportional part of the work they have done" , " Success is not always proportional effort in this professional career ” .
Let's take the first of the examples to understand the concept. Let us suppose that, in a certain country, there was an inflation of 15% in the last year; In other words, we can understand that your cost of living went through an increase of 15% during the last twelve months. When negotiating a wage increase , workers decide to start from a floor that, at least, covers said increase in the cost of living. Therefore, they seek a salary increase of not less than 15% so that said increase is proportional to inflation and implies not losing their purchasing power.

In the context of grammar , it is known as a proportional adjective or multiple adjective that which reflects the number of times a certain quantity is contained in another. The expression "In my new job I earn twice as much as in the previous one" reveals that the person in question receives, in his current job, twice as much money as in the job he had previously.
When two quantities are compared , depending on the point of view, it is possible to conclude that they are directly proportional or inversely proportional .
One magnitude is directly proportional to another when any increase or decrease suffered by the first is proportionally reflected in the second. This is also known by the name of direct proportionality and is simply defined as the relation to more corresponds to more and to less, less . On the other hand, one magnitude is inversely proportional to another if its increases are reflected in decreases and vice versa; in this case, more corresponds to less and less, more .
An everyday example of directly proportional magnitudes is found in commercial activity : the normal thing is that the more products we buy, the higher the total amount of the transaction; being stricter, the number of units of a given product tends to directly multiply the price of the unit (except for the cases in which a discount is applied, although this multiplication must be performed before applying it).

Inverse proportionality is more difficult to understand, as it requires slightly more abstract or complex examples. Suppose we have a basket full of apples and we want to count both the percentage of its content, which is initially 100, and the number of apples that a subject eats; For each one consumed, the percentage will always be reduced in the same proportion, such that the more units eaten, the lower the content of the basket.
As can be seen, these mathematical concepts are applied in everyday life, although not always in an obvious way, but they are part of our analysis tools. In fact, we can use the following examples to understand how subtle the presence of one magnitude inversely proportional to another can be: "The closer I get to mathematics, the less fear they cause me" , "Every page I read makes me feel that I understand less " , " No matter how many opportunities I give him, he always wastes them and that takes him further and further away from me .
