to do them? what do you mean?
to get the integers take all the positive numbers 1, 2, 3 .....
now take the negative of each one of those -1, -2, -3....
now add 0.
All of those numbers together make up the integers.
take any two integers a and b, where b isn't 0. a/b is then a rational number
To get the irrational numbers take all of the real numbers.
Now toss out the rational numbers. What's left is the irrational numbers.
