Hey mate......
here's Ur answer....
1) Natural number is an integer greater than...
Example = 1
2) Whole numbers are positive numbers including zero.
Example = 0
3) Composite numbers has factors in addition to one and itself.
Example = 2 × 3
4) Numbers, which do not have any common factor between them other than one, are called co-prime numbers.
Example = 5
5) Number that can be rewritten as a simple fraction is a rational number.
Example = 7
6=) Number that can not be rewritten as a simple fraction is a N irrational number.
example = Root 2 /5
7) A complex number can be imaginary if its real part is equal to zero.
Ex = 0 + 5i
Hope it Helps❤

natural number :
the numbers 1,2,3,4 .. are called natural or counting numbers. the set of natural numbers is denoted by N .
example {1 ,2,3,4...}
whole number :
Natural numbers including zero are called whole numbers . the set of whole numbers is denoted by W.
thus, example W= { 0,1,2,..}
composite number :
the natural numbers excluding 1 which are not prime are known as composite numbers.
note:
a) '1 is neither prime not composite.
b) '2 is the only even number which is prime.
c) '4 is the smallest composite number.
co- prime number
two numbers are co- prime if their HCF is 1 . for example 3 & 4, 3 & 10, 12 & 35, etc.
rational number :
those numbers are that can be represented in the form p/ q where p, q are co- prime and q ≠ 0 .(because division by zero is invalid).
when q≠1 and p, q have no common factor except 1 (where p, q are both positive) the rational numbers are called fractions.
rational number when represented in decimal form are either terminating or non- terminating but recurring.
ex., 5/4 = 1.25 (terminating in zeros)
5/3= 1.666.. ( non terminating but recurring)
Irrational numbers:
numbers which can't represented in form p/q where p, q integers and q≠0 ) are called irrational numbers.
in decimal representation , they are neither terminating nor recurring hence, all surds fall in this category.
ex., √2, 5 etc
note:π≠22/7,22/7 is only an appropximate value of π in terms of rational numbers taken for convenience .
actually π = 3.14159 ...( which is a non terminating and non recurring decimal number.)
complex number:
complex number is usually denoted by z and set of complex number represented by c.
