    The rule is rounding.

    9.82 correct to 3 s.f. means it has been rounded to 3 s.f. so you just find the highest number that rounds down and the lowest that rounds up.

    For 9.82, that would be:

    9.82499999999999 and so on
    Which is just written as 9.825 (upper bound)

    And 9.815.

    9.82
    ub=9.825
    lb=9.815
    4.26
    ub=2.465
    lb=2.455
    That's all correct.
