Research Type Theoretical In this paper, we propose to study the up to a fraction relaxation of EF and PROP, when a mixture of divisible and indivisible goods are allocated. We show that an EFα allocation may not exist and a PROPα allocation always exists. Thus we would like to understand to what extent EFα needs to be relaxed and PROPα can be strengthened, namely EFf(α) and PROPf(α), so that a fair up to a fraction allocation exists. In Section 3, we study the up to a fraction relaxation of EF, i.e., EFα and EFf(α). We first prove that f(α) = Θ(n)α is necessary and sufficient to satisfy EF by removing f(α) fraction of a good. We find that any EFM allocation is EFnα, and thus an EFnα allocation always exists (by [Bei et al., 2021a]). The guarantee of EFM cannot be improved even when agents have identical valuations. On the other hand, we prove that at least n2 4(n 1)α fraction of the good has to be removed in order to satisfy EF, and thus our results are tight up to a constant.
