Why you report it?
root 12 is not a rational number as root 12 and root 3 are not integer . This is true or false
√12=2√3
As√3 is an IRRATIONAL NUMBER
And rational*irrational=irrational
So √12 is not a rational
You have a wrong concept that 1.5 is also not a integer .but it is a rational number as it can be written as p/q form 1.5=15/10=3/2
If a number can be written as p/q where p and q areINTEGER and G.C.M of p,q is 1 then it is a rational number.
Those real number who cannot written as previous they are irrational.
