A teacher writes 22/7 and π on the board and asks the class which one is irrational. Which statement is correct?

Question

Accepted Answer

22/7 is rational; π is irrational. 22/7 is only an approximation of π.. 22/7 is a ratio of integers, so it is rational. π cannot be written as a ratio of integers, so it is irrational; 22/7 is merely a close approximation.
