Rational numbers properties:
Rational numbers are the numbers that can be expressed as a fraction of two integers, a/b, where b ≠ 0. These fractions are represented on a number line between 0 and 1, with the numerator representing the part of the unit representing the denominator.
Properties of rational numbers:
Addition and subtraction: Adding or subtracting rational numbers results in a rational number.
Multiplication: The multiplication of rational numbers is also a rational number.
Division: Dividing rational numbers results in a rational number, except when the denominator is 0.
Exponentiation: The exponentiation of rational numbers is also a rational number.
Rational numbers are closed under addition and subtraction. This means that the sum or difference of two rational numbers is also a rational number.
Rational numbers are closed under multiplication. This means that the product of two rational numbers is also a rational number.
Rational numbers are closed under exponentiation. This means that the exponential of a rational number is also a rational number.
Rational numbers are a subset of real numbers. This means that every real number can be expressed as a rational number
