Any number we use is real (there are others like complex, but they are very rarely used).
If a number consists only of sign and digits (like 0;327;98765;-5;-789 and so on) then it is a whole number or integer.
A rational number is any number that can be repesented as a fraction. So every integer is also a rational number (because it can be written as a fraction with the denominator 1) 5=51;27=271
An irrational number is any real number which cannot be represented as a fraction (like √3,π,log3 and others)
0.8=810=45 so it is a rational number (but also real)
