You're assigning an expression to a variable and ‘n/m <...>’ is
available in expressions as far as I recall.

This should put you on the right track.

    $ cat third.tr
    .PS
    B: box
    A: 1/3 <B.ne, B.se>
    print A
    print A.x
    .PE
    $
    $ pic <third.tr >/dev/null
    0.75, 0.0833333
    0.75
    $
