hyphenation - Hyphenating spelled-out fractions with large numerators and/or denominators

I find myself in the awkward position of needing to systematically spell out fractions where the numerator, the denominator, or both have three or more digits, and I'm not sure about the hyphenation. For example, 124/145:

• one-hundred-twenty-four one-hundred-forty-fifths?


• one hundred twenty-four one hundred forty-fifths?


• something else?
