Symbol for rational numbers

Which of the numbers in the following set are

The set of all rational numbers includes the integers since every integer can be written as a fraction with denominator 1. For example −7 can be written −7 / 1. The symbol for the rational numbers is Q (for quotient), also written . Real numbers Each repeating decimal number satisfies a linear equation with integer coefficients, and its unique solution is a rational number. To illustrate the latter point, the number α = 5.8144144144... above satisfies the equation 10000α − 10α = 58144.144144... − 58.144144... = 58086, whose solution is α = 58086 9990 = 3227 555. A rational number is defined as a fraction of two numbers in the form of \[\dfrac{p}{q}\] where p and q can be any integer but q is not equal to 0. Algebra is the branch of mathematics that deals with symbols and variables. Rational numbers consist of all types of numbers including Natural numbers, Whole numbers, also 0, etc. Integers …

A combination of a real and an imaginary number in the form a + bi, where a and b are real, and i is imaginary. The values a and b can be zero, so the set of real numbers and the set of imaginary numbers are subsets of the set of complex numbers. Examples: 1 + i, 2 - 6 i, -5.2 i, 4. They can be positive, negative, or zero. All rational numbers are real, but the converse is not true. Irrational numbers: Real numbers that are not rational.

There is no generally accepted symbol for the irrationals. This is most likely because the irrationals are defined negatively: the set of real numbers that are not rational. Real numbers are denoted by R and rational numbers are denoted by P. Remember that a whole number can be written as one integer over another integer. The integer in the denominator is 1 in that case. For example, 5 can be written as 5/1. The natural numbers, whole numbers, and integers are all subsets of rational numbers.There is a difference between Rational Numbers and Irrational Numbers.
