Rational number

Rational numbers:

These can be written as $\frac{p}{q}$, where both p and q are integers and q is not equal to zero. The following are the qualities of rational numbers: closure, commutative, distributive, associative, identity, inverse.

Closure:

The outcomes of mathematical operations like addition, subtraction, and multiplication operations for two rational integers, say a and b, yield a rational number. When it comes to these mathematical operations, we can claim that rational numbers are closed. Example:

$\frac{2}{3}$+$\frac{3}{2}$= $\frac{13}{6}$
