  1. any number that can be expressed as a simple fraction of the form a/b, where b ≠ 0 is rational

    rational --- from ratio --- a: b or a/b

    A number which cannot be expressed as a simple fraction in the above form is irrational
    irrational --> not rational
    (irresponsible -- not responsible)

    Any decimal which terminates is rational
    any decimal which has a repeat is rational
    any decimal which does not show any repeating decimals and which is never-ending is irrational

    e.g.
    4/7 --- rational
    3.454545... rational
    2.6789789789... rational
    4.56556555655556... irrational
    π --- irrational
    √5 or any square root of a number which is not a perfect square is irrational

    √16 -- rational, but √17 -- irrational

  21. a girl, how much money do you want to bet these celebrities don't know what an irrational number is. Yes, you won't need this stuff if you ae going to study rocks. But what if that on time, that one time, you need to know how to solve one. Now the whole celebrities stuff. Most celebrities are famous because of how they look, or how good their acting is in a movie. You look at someone like Tom Cruise. He only acts, but he is still an incredibly smart man. Now other celebrities such as the Kardashians will be forgotten in 50 years. But someone like Elon Musk won't be forgotten because of what he has done.
