## Rational Numbers Class 8 Maths Formulas

**Rational Number**: A number is called rational if we can write the number in the form of $\frac{p}{q}$, where $p$ and $q$ are integers and $q \neq 0$ i.e., $1=\frac{1}{1}, 2=\frac{2}{1}, 0=\frac{0}{1}$ and $\frac{5}{8}, \frac{-3}{14}, \frac{7}{-15}$ are all rational numbers.- Additive Identity: $(a / b+0)=(a / b)$
- Multiplicative Identity: $(\mathrm{a} / \mathrm{b}) \times 1=(\mathrm{a} / \mathrm{b})$
- 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 $b, a x$ $b$ 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 $b \neq b-a$.
- 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 $b,(a / b) \neq$ (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, $(a$ $-b)-c \neq a-(b-c)$
- Associative Property - Multiplication: For any rational number $a, b$, and c, $(a \times b) \times c=a \times(b \times c)$.
- Associative Property - Division: For any rational numbers $a, b$, and $c$, ( $a$ /b) / $\mathrm{c} \neq \mathrm{a} /(\mathrm{b} / \mathrm{c})$.
- Distributive Property: For any three rational numbers $a, b$ and $c, a \times(b+c)$ $=(a \times b)+(a \times c)$.
