Abstract: Applying the representations of {1}-inverse, {1,3}-inverse, {1,4}-inverse and {1,5}-inverse, the representations of the star, left-star, right-star and the Sharp partial orderings were given by using rank equalities, respectively.

Key words: minus partial ordering, star partial ordering, Sharp partial ordering, rank
