    Just to add a bit more theory, repeating decimals can be replicated by taking the replicating part and dividing by the number of 9's in the length of the repeating section.

    For example:
    0.4444... = 4/9
    0.373737... = 37/99
    0.123123123... = 123/999

    So for your example, the fraction is 3 + 45/99, which ebaines then simplified.
