Example: "In the study, we found that a different fraction of participants preferred option A over option B."
Alternatives: "a distinct portion of" or "another segment of".
This time, a different fraction of tags light up, and another picture is taken.
The same amount of mass has disappeared, though a different fraction of it may have been carried off by the neutrinos.
Note that, while a gray (i.e. energy-independent) correction is applied to each shell, the overall empirical correction for the full HRMA absolute effective area is not energy-independent, since different shells contribute a different fraction of the total effective area at different energies (see Figure 4.3).
Four different solvents were compared, each containing a different fraction of CO2.
Moreover, CTCs are not always present and may represent a different fraction of cells from the bulk metastatic tissue.

This paper presents a study on compactness of four different fractions of scrap tyre rubber (A: 0.1 – 1 mm, B: 0.5 – 2 mm, C: 2 – 5 mm and D: 10 – 40 mm) in the standard Proctor test.
Since the optical properties of the substrate and the metal atoms, deposited, are quite different, fractions of a monolayer coverage can easily be detected even in the presence of other reactions like hydrogen evolution.
