Answer 1

Step-by-step explanation:

Any number that can be written in the form of p ⁄ q where q ≠ 0 are rational numbers. It posses the properties of:

Additive Identity: (a ⁄ b + 0) = (a ⁄ b)

Multiplicative Identity: (a ⁄ b) × 1 = (a/b)

Multiplicative Inverse: (a ⁄ b) × (b/a) = 1

Closure Property – Addition: For any two rational numbers a and b, a + b is also a rational number.

Closure Property – Subtraction: For any two rational numbers a and b, a – b is also a rational number.

Closure Property – Multiplication: For any two rational numbers a and b, a × b is also a rational number.

Closure Property – Division: Rational numbers are not closed under division.

Commutative Property – Addition: For any rational numbers a and b, a + b = b + a.

Commutative Property – Subtraction: For any rational numbers a and b, a – b ≠ b – a.

Commutative Property – Multiplication: For any rational numbers a and b, (a x b) = (b x a).

Commutative Property – Division: For any rational numbers a and b, (a/b) ≠ (b/a).

Associative Property – Addition: For any rational numbers a, b, and c, (a + b) + c = a + (b + c).

Associative Property – Subtraction: For any rational numbers a, b, and c, (a – b) – c ≠ a – (b – c)

Associative Property – Multiplication: For any rational number a, b, and c, (a x b) x c = a x (b x c).

Associative Property – Division: For any rational numbers a, b, and c, (a / b) / c ≠ a / (b / c) .

Distributive Property: For any three rational numbers a, b and c, a × ( b + c ) = (a × b) +( a × c).
