Recall that the natural numbers are contained in the whole numbers that are contained in the integers that are contained in the rational numbers, that are contained in the real numbers, and the irrational numbers are those real numbers that are not rational numbers.
From the data set:
There are no natural numbers in the data set.
The only whole number is 0.
The integers are -11,0.
The rational numbers ( numbers of the form a/b, where a and b are integers) are -11, -2/7, 0, 0.3=3/10,√ 36=6.
The irrational numbers are √3 and π, as they cannot be written as a/b.
All the numbers in the data set are real numbers.
