put this solution on YOUR website!there are many set of numbers:
Count number set = {1,2,3,4,..........}
N=Natural Numbers set ={0,1,2,3,4,......}
It consists of count numbers set with zero
Z= Integer numbers set = {....,-3,-2,-1,0,1,2,3,....}
Z= All natural numbers set with negatives.
Q= Rational numbers set ={a/b: a,b are integers, b doesn't equal zero}
Q= All integers with all decimials and fractions
Q`=Irrational numbers set (numbers cannot be in Q)
Q` doesn't contain any number from Q "it contains numbers as Sqrt3, Pi, etc"
R=Real numbers set"All numbers represented on number's line"
R contains all previous sets
so we find 3 1/2 in Q, R only and it doesn't contained in N or Z
