1. Rational numbers are closed under addition, subtraction, multiplication and division (if the divisor is not zero).
2. Subtraction of rational number is neither commutative and associative.
3. When 0 is subtracted from a rational number, the rational number itself is obtained i.e. $\frac{P}{q}-0 = \frac{P}{q}$.
4. Commutativity and associativity of division of rational is not true .
5. The additive inverse of the rational number $\frac{a}{b}$ is $\frac{-a}{b}$.
6. Reciprocal of 0 is not possible.
7. The product of any rational number with 0 is 0.
8. All fractions and integers are also rational numbers.
9. There are countless rational numbers between any two given rational numbers.
