Consider      a    b    =      c    d    nwhere   b  ,  d  ≠  0. Then   n  =            a      d              b      c        .Now if you have,      a    b    =      c          d      n      Then  n  =            c      b              d      a      Both results were obtained by cross multiplying in order to isolate the unknown variable n
