👉 Rationality is a concept in mathematics that describes how numbers are expressed and manipulated. It refers to the property of being able to express any number as a ratio of two integers, where the denominator is not equal to zero. The most basic example of a rational number is the decimal 0.75, which can be written as "3/4" because it represents the fraction of three parts out of four total parts. Other examples include fractions such as 1/2 and 4
