What is the difference between a rational number and an irrational number?

Rational numbers can be written as a fraction (p/q) and have terminating or repeating decimals (like 0.5 or 0.333...), while irrational numbers cannot be expressed as a simple fraction and have non-terminating, non-repeating decimals (like 𝜋 𝜋 or 2 2 √ ). Essentially, "rational" means "ratio" – expressible as a ratio of two integers.
