eating a whole fruit

Question

When eating a grapefruit, should one make the blessing on the whole fruit first and then cut a slice and eat,or should the blessing be made on the slices so that one can eat the fruit immediately after the blessing?Whats the best way to praise Hashem on a whole ,or slices.Is this similar to making the blessing on challah friday night?
