discrete structures

Let A = {1, 2, 3, 4, 5, 6, 12} and define the relation R on A by m R n iff m|n. Write the definitions of the properties, reflexive, antisymmetric and transitive and the use the definitions to determine whether each property holds for this relation. (a) Is this relation a partial ordering relation? Why? If so, draw its Hasse diagram. (b)Write the (boolean, that is, the yes/no) matrix of this relation. I know the definitions but am having difficulty in determining the usage for each. I'm really stuck on this one.
