Final answer:
Rational numbers and their properties, including closure under operations like addition and distributivity.
Explanation:
Rational Numbers are numbers that can be expressed as a ratio of integers, such as 2/1 or 3/4. They include integers and fractions. Rational numbers exhibit various properties, including closure under addition, subtraction, multiplication, and division.
One property is the closure under addition where the sum of two rational numbers is also a rational number: a/b + c/d = (ad + bc) / bd.
The property of distributivity states that a(b + c) = ab + ac for rational numbers a, b, and c.
