Notes on Rational Numbers--

Rational Number- Any number that can be expressed in the form of p/q, where p and q are integers and q is not equal to 0, is known as rational number.

The collection or group of rational numbers is denoted by Q.

Properties of a Rational Number

• Closure-Rational numbers are closed under addition, subtraction and multiplication. For eg.- If p and q are any two rational numbers, then the sum, difference and product of these rational numbers is also a rational number. This is known as the closure law .

Commutativity- Rational numbers are commutative under addition and multiplication. If p and q are two rational numbers, then:
Commutative law under addition says-p + q = q +p.

Commutative law under multiplication says- pxq= qxp

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.

Associativity- Rational numbers are associative under addition and multiplication. If p,q and r are rational numbers, then:
Associative property under addition: p + (q + r) = (p + q) +r

Associative property under multiplication: px(qxr)=(pxq)xr

Role of zero and one-0 is the additive identity for rational numbers. 1 is the multiplicative identity for rational numbers.

• Multiplicative inverse-If the product of two rational numbers is 1, then they are called multiplicative inverse of each other.
Eg. 4/9*9/4 = 1
