Pi.... it means 3.14...etc
It is very obvious that many people think it is irrational.
BUT, the definition of a rational number is that it can be put it in an A over B form.... or a fraction
Pi = 7 over 22 = 7 divided by 22 = 7/22 ....etc
So... rational or irrational... ill ask my Math teacher

π = 22/7 and 22/7 is rational.
π is rational
3.14 is an approximation to 22/7

Irrational Pi is not really 22/7 it's just an approximation. Pi is close to 22/7 but not exactly.In the real number Pi there are no repeating numbers etc.

True! But, however, 7/22 does not equals to 3.1415926
nor does 22/7, therefore, pi is a irrational number

Divide 22 by 7 = 3.142857142857... which is a repeating decimal. 22/7 is an approximation only of pi. Pi is a non repeating decimal and is therefore irrational.

π is most definitely an irrational number
3.14 and 22/7 are common approximations used in mathematics but neither are correct .. in fact 22/7 does NOT equal 3.14 (or more correctly 3.14159....)
try it on a calculator divide 22 by 7.

Pi is an irrational number. 3.14 is just an estimate, because pi is actually a unending never repeating decimal.

irrational
it cannot be precisely represented by a fraction with integers for both numerator and denominator.
