-22/7, -pi, -3.3 (with a dot on top of the second 3), -3.142
-pi is the only irrational number since its value cannot be expressed as the fraction of two integers.
In decimals,
-22/7 = -3.142857...
-pi = -3.141592...
-3.3 dot = -3.333333...
-3.142 = -3.142000
Clearly -3.3 dot is the smallest (because 3.333333... is bigger than the rest but the negative sign makes it smaller than the rest).
Between the others, -3.142857... is the next one, followed by -3.142000 and -3.141592...
So, in order from smallest,
-3.3 dot, -22/7, -3.142, -pi
