Natural number can be a whole number because Natural number starts from 1 and whole number starts from 0 which includes 1
Natural no: 1,2,3,4,5,.....
Whole no: 0,1,2,3,4,5,......
The bold numbers which are presented in the whole number are nothing but the natural numbers except 0
Therefore these 1,2,3,4,5,.... are the natural numbers which are coming in the whole numbers
Integer can be a Rational number because every integer can Be expresses as p/q form eg: 3 is integer can be expressed as 3/1
-4 is an integer and can be written as -4/1 where p is -4 and q is 1
Rational number can not be an Integer because 2/5 is not an integer but it is a rational number as p is 2 and q is 5 but we know that integer does not have p/q form.
