WebSo we can tell if it is Rational or Irrational by trying to write the number as a simple fraction. Example: 9.5 can be written as a simple fraction like this: 9.5 = 19 2 So it is a rational number (and so is not irrational) Here are some more examples: Square Root of 2 Let's look at the square root of 2 more closely. WebThat is, we suppose that the square root of any non-square number is rational. So $\sqrt{n}$=ab , where a,b∈Z+,b≠0. We also suppose that a≠0, otherwise ab=0, and n will be a square number, which is rational. WebNow we square both sides of √2 = a/b to get 2=a²/b² and from there it is a short journey to show that since 2=a²/b², it means that both a and b must be even numbers which means they have a 2 in common.
