Question: is pi rational in any base?
Answer: Pi is “irrational” which means that it can't be represented by the ratio of two integers… there is no set of two whole numbers that can be divided by each other to make pi. Since an integer is still an integer in any base system - pi will still be irrational. ... So in base 3, the value of 1/3 in decimal is 0.1 in base 3.
