Answer 2

The Irrational numbers

Explanation:

The so called "irrational numbers" cannot be written as a fraction of the type p/q. These are for example the square root of numbers that are NOT perfect squares (i.e.
`√(2) , \, √(3) ,\, √(5) , \,√(6) ,\,√(7) ,\, \pi`, and many others.

Their particular name "Irrational Numbers" derives actually from the fact that they cannot be written as a "ratio" of two integer numbers.
