Ratio :
Ratio refers to the comparison of two or more integers. It performs as a measuring tool to show how large or small one amount is in comparison to another. In a ratio, two quantities are compared by using division. When comparing two objects that are similar to one another in terms of units, ratios are the numerical numbers used. For example, we can compare a pencil's length to a pen's length. We can't compare two things which are not similar to each other.
