• Examples of rational numbers include 1/2, -3/4, 0, 5, and -2.

π is irrational because it cannot be expressed as a fraction and its decimal representation is non-repeating and non-terminating.

• An irrational number cannot be expressed as a fraction or a ratio of two integers.

• π is a transcendental number, meaning it is not the root of any non-zero polynomial equation with integer coefficients.

• The decimal representation of π goes on forever without repeating or terminating, making it ...read more

22/7 is an approximation of the mathematical constant π.

• 22/7 is a commonly used approximation for π in many mathematical calculations.

• The actual value of π is an irrational number and cannot be expressed exactly as a fraction.

• The decimal representation of π goes on infinitely without repeating.

• Using 22/7 as an approximation for π is accurate enough for most practical purposes.
