: Have you ever compared two things? Yes, of course. You always keep on comparing things, and this is how human psychology works. You are well aware of the ratio sign but unaware of it. Here, the question arises what this article is for? A valid question, yeah!

However, you don’t know to compare things. You tend to use ratio in mathematics and other subjects. People are applying it in their lives but unaware of it. Also, it’s nearly possible to automatically learn the correct usage of ratios except for those who have “learned “in syllabus books.

In this article, we dive deeper into the details of ratio from its meaning to usage along with codes in computer languages being used for ratio symbol.

The symbol of ratio is :. There is no validity for its origin as it’s commonly used, so no sources referred to its exact origin when it was first used. However, a Greek mathematician Euclid described it for the first time as per reports. When it comes to its earliest known use, π sign was used for the ratio of circle’s circumference in 1706 by William Jones.

As we introduced the ratio sign clearly above, let’s find out what does it mean in mathematics and what it actually is.

Do you get an idea from the above discussion? Yes, it completely makes sense to the reader. You’re actually using this method but unaware which method you are following. The comparison between things may be of measurements, length, width, weight. In most cases, both quantities are taken to be as positive. However, exceptions are still there.

Sometimes, for comparison purposes, fraction sign alternatively to ratio symbol.

A: B = A/B here, the first term A is called **antecedent**, and the second term B is **consequent**.

In simpler terms, it allows us to value two or more things at the same time in an easier apart from writing down in words. Therefore, math’s symbols have an edge and benefit of their usage.

When comparing the material in any construction site, then ratio is used.

Sand: cement: dirt = 2:3:4 this is how this sign is used to compare more than two values at the same time.

Its calculation process is quite easy to learn and needs a little practice on a different question. You might probably have used its calculation process before but don’t know that you actually used ratio method.

For example there are 100 students in the class in which 60 are boys and the remaining are girls. Now, if we are to determine the ratio of boys and girls we will proceed as follows:

Total students= 100

Total boys= 60

Total girls= 100-60=40

Ratio= 60:40= 3:2

Another method to comparing things is by fraction method. It serves the same purpose as that of ratio sign. 3: 10 can by written as 3/10=0.333

Typing ratio sign is a child’s play. But often, people confuse it while typing on the computer. There are different applications and gadgets where you need to type it now or never. So, let’s learn the procedure for each one of them.

There are different codes for ratio symbols by which the computer takes no time to understand what we want to type in ratio sign. In computer, character encoding standards are there that help in the association of different codes with a variety of signs. The is given below :
