4. The sum of any two rationals is always a rational number.
5. Irrationals cannot be expressed as a ratio of integers and therefore are not included in the set of rationals.
6. The decimal expansion of some rationals is finite, while others are infinite and repeating.
7. When comparing two rationals with the same denominator, the one with the larger numerator is considered to be greater.
8. The set of rationals is denoted by the symbol Q.

14. The set of rationals is countable, meaning that it can be placed in a one-to-one correspondence with the set of natural numbers.
15. The order of rationals is preserved under addition and multiplication, meaning that if a > b and c > 0, then a + c > b + c and a c > b c.
16. The set of rationals is dense in the real number system, meaning that between any two real numbers there exists a rational number.
17. The sum of any finite set of rationals is always a rational number.
18. Some famous irrational numbers include pi and the square root of 2, which cannot be expressed as a ratio of integers.
19. Rationals are closed under addition, subtraction, and multiplication, but not division by zero.
20. The product of any finite set of rationals is always a rational number.
21. The opposite of a rational number is also a rational number.

31. An equivalent fraction is a rational number that can be obtained by multiplying the numerator and denominator of a given fraction by the same non-zero integer.
32. Rationals can be represented geometrically on a number line.
33. The sum of any set of rationals where the denominators have a common multiple is also a rational number.
34. The product of any set of non-zero rationals can be written in lowest terms by canceling out common factors in the numerator and denominator.
