Is Pi (π) a Rational or Irrational Number?

To understand why Pi is irrational, you must know the rules:

• A Rational Number is any number that can be written perfectly as a simple, exact fraction (p/q). For example, 1/2 is rational because its decimal is exactly 0.5 and it stops.
• An Irrational Number is a massive, chaotic decimal that goes on forever into infinity without EVER stopping (Non-terminating) and without EVER falling into a predictable repeating pattern (Non-repeating). You physically cannot write it as a perfect fraction.

If Pi is irrational, why do we use 22/7 in school? This is the biggest lie taught in basic geometry. Pi is NOT exactly equal to 22/7.

• The fraction 22/7 is a rational number. If you divide it on a calculator, it becomes 3.142857... and eventually the digits repeat.
• The true value of Pi is 3.1415926535... and the decimals go on randomly for trillions of digits into infinity without ever stopping or repeating.

Teachers only use 22/7 because it is 'close enough' to the real Pi to get a basic answer, but in high-level physics and computers, it is considered completely mathematically inaccurate.

Pi is a geometrical constant found in nature. No matter how massive or tiny a perfect circle is (from a microscopic atom to the orbit of a massive planet), if you take the distance around the circle (Circumference) and divide it by the distance across it (Diameter), the answer will ALWAYS be the infinite, irrational number 3.14159...
