What Makes a Number 'Irrational'?

Irrational numbers are like magic numbers that never end and never repeat. They can’t be written as a simple fraction, like 1/2 or 3/4. A famous irrational number is π (pi), which goes on forever without repeating: 3.1415926535... It’s like trying to catch a fish that keeps swimming away!
