I think it means the latter. There used to be a classic construction in the old geometry Regents that required a student to divide a given segment into any number of congruent parts.

In your example, the ratio is 3:4 so that there will be 7 parts. Then depending on how the question is worded, there would be two answers.

If you need further info as to how to do the construction, let me know.
