    Hi I'm having a hard time on this POTW. Can you guys help me with it?
    this is the question

    Give a list of 6 real numbers on a number line from least to greatest such that the first number is a rational number, the second number is an integer, the third number is an irrational number, the forth number is a negative, the fifth number a a natural number, and the sixth number is a whole number.
    And place it on a number line

    Thank you in advance :)

    For example:

    1. rational: -5/2 = -2.5
    2. integer: -2
    3. irrational: -sqrt(2) = -1.414...
    4. negative: -1
    5. natural: 1
    6. whole: 2

    Placing those on a number line shouldn't be too hard.

    I have another one guys, this one is a problem i don't understand. I have an answer but I'm really not sure about it. THX in advance. And this is jus the important part of the problem.

    As the season goes on and he pitches more games, his ERA will constantly change in value, but it always represents the average number of runs he would give up over nine innings of pitching. If he's given up 11 runs after pitching a total of 18 innings, his ERA would be 5.50.

    I recently attended a Red Sox game, and one pitcher had an ERA of 13.50 when he came into the game. After he got one batter out, his ERA dropped to 13.00. Note that since there are three outs in an inning, one out represents a third of an inning pitched.

    How many innings had that pitcher pitched before he came into the game I saw?

    I stink at baseball, so I don't fully inderstand what ERA is still, but I guessed by pluggin some numbers together and got like 121...
    This must be wrong, though...
