lukecrayonz · Answer

natural, 1
integers, 0,1

lukecrayonz · Answer

and all are real

unklerhaukus · Answer

all are rational

unklerhaukus · Answer

which is a rational number

lukecrayonz · Answer

Wait, yes, sorry, was thinking of something else

anonymous · Answer

$$ 0, 1, \frac 1{12}, \frac 1{16}, \frac 1{20} $$

There is no imaginary part. Hence all are reals.

They are also rationals since each of them can be written in the form of $\frac pq $ where $p$ and $q$ are integers and $q\neq 0$

anonymous · Answer

The set of Naturals usually start from 1, but according to some convention we also consider 0 to be natural. Please check which one is expedient for you.

anonymous · Answer

Here only 0 and 1 are integers.

anonymous · Answer

None, is irrational since the set of rational and irrationals set are disjoint. REF: An irrational number is any real number that cannot be expressed as a ratio a/b, where a and b are integers, with b non-zero, and is therefore not a rational number.
