     Two numbers have a product of 1 and the sum of their reciprocals is 2 1/2.

     x (y) = 1

    1/x + 1/y = 2 1/2 

     1/x + x = 2 1/2

    Solutions: 

     x = 2, y = 1/2

     x = 1/2, y = 2

     The 2 numbers are 2 and 1/2

    What's this gibberish regarding reciprocals?;

    The 2 numbers are obviously a and (1/a).
