@hammy_1 Hi,

Integers are positive and negative natural numbers like -4,3,10 .... any number from -infinity to + infinity, without involving fractions.
rational numbers are ratio of 2 integers which do not simplify to an integer.
like 4/2 is not rational, because it simplifies to integer = 2
but 5/2 is a rational number.
so its real, rational and not integer.
(real number are those which do not contain imaginary unit "i" in them.)
