The set of all rational numbers, often referred to as "the rationals", the field of rationals or the field of rational numbers is usually denoted by a boldface Q (or blackboard bold $${\displaystyle \mathbb {Q} }$$, Unicode /ℚ); it was thus denoted in 1895 by Giuseppe Peano after quoziente, Italian for "quotient". In old books, classic mathematical number sets are marked in bold as follows $\mathbf{Q}$ is the set of rational numbers. If p/q is multiplied by s/t, then we get (p×s)/(q×t). Every Natural Number is a Rational Number but it’s not the same in the case of Rational Numbers. Division: If p/q is divided by s/t, then it is represented as: Since a rational number is a subset of the real number, the rational number will obey all the properties of the real number system. Rational numbers are all real numbers, and can be positive or negative.A number that is not rational is called irrational.. Can be expressed as the quotient of two integers (ie a fraction) with a denominator that is not zero. Irrational numbers contrasted the rationale numbers, such as cosines, sines etc. Example 1: Insert a rational and an irrational number between 2 and 3. Since 0 does not have a repeating decimal, it is a rational number. Whole numbers, integers, fractions, terminating decimals and repeating decimals are all rational numbers. Rational numbers are denoted Q . 1. When the rational number (i.e., fraction) is divided, the result will be in decimal form, which may be either terminating decimal or the repeating decimal.
