Answer 2

Answer:

$Rational Number- Any Number that can be expressed in the form p/q , where p and q are integers and q ≠ 0, is known as rational number. The collection or group of rational numbers is denoted by Q.</p><p></p><p>Properties of a Rational Number</p><p></p><p>▪  Closure- Rational numbers are closed under addition, subtraction and multiplication. For eg.- If p and q are any two rational numbers, then and the sum, difference and product of these rational numbers is also a rational number. This is known as the closure law</p><p></p><p>▪  Commutativity- Rational numbers are commutative under addition and multiplication. If p and q are two rational numbers, then:</p><p></p><p>Commutative law under addition says- p + q = q + p.</p><p></p><p>Commutative law under multiplication says p x q = q x p.</p><p></p><p>Note- Rational numbers, integers and whole numbers are commutative under addition and multiplication. Rational numbers, integers and whole numbers are non commutative under subtraction and division.</p><p></p><p>▪  Associativity- Rational numbers are associative under addition and multiplication. If a, b, c are rational numbers, then:</p><p></p><p>Associative property under addition: p + (q + r) = (p + q) + r</p><p></p><p>Associative property under multiplication: p(qr) = (pq)r</p><p></p><p>▪  Role of zero and one- 0 is the additive identity for rational numbers. 1 is the multiplicative iden}{?} </p><p>▪  Multiplicative inverse- If the product of two$
