When all is irrational, the only thing you can eat and probably live is pi since it's a number.

π \pi is not equal to 22 7 \frac{22}{7} because that is an approximation. The actual π \pi is an irrational number, so it cannot be expressed as ratio of two integers.

Therefore the correct form is : π < 22 7 \large \pi \ < \ \dfrac{22}{7}
