Irrational Numbers Symbol. Generally, we use the symbol “P” to represent an irrational number, since the set of real numbers is denoted by R and the set of rational numbers is denoted by Q. We can also represent irrational numbers using the set difference of the real minus rationals, in a way $\text{R} – \text{Q}$ or $\frac{R}{Q}$.Any rational number can be represented as either: a terminating decimal: 15 8 = 1.875, or. a repeating decimal: 4 11 = 0.36363636⋯ = 0. ¯ 36. We use a line drawn over the repeating block of numbers instead of writing the group multiple times. Example 1.2.1: Writing Integers as Rational Numbers. The symbol for the real numbers is R R . Irrational numbers: All the real numbers that are not rational are called irrational numbers. These numbers cannot be ...Set of rational numbers. In old books, classic mathematical number sets are marked in bold as follows. $\mathbf{Q}$ is the set of rational numbers. So we use the \ mathbf command.

The symbol for the rational numbers is Q (for quotient), also written . Real numbers Finally, as you might imagine, the symbol for the nonpositive integers is Z−. I’m unaware of any symbol for the strictly negative integers, but you could write them as Z− −{0}. Now, a rational number is a number that can be written as one integer divided by another. The set of rational numbers is represented as Q. TheIf a number can be expressed as a fraction where both the numerator and the denominator are integers, the number is a rational number. Some examples of rational numbers are as follows. 56 (which can be written as 56/1) 0 (which is another form of 0/1) 1/2. √16 which is equal to 4. -3/4. 0.3 or 3/10. -0.7 or -7/10. (Honsberger 1991). The probability that a random rational number has an even denominator is 1/3 (Salamin and Gosper 1972).
