This road sign was found heading west on I-10 in Phoenix, Arizona.

The road sign says...

   +----------------------+
   | University Dr    1/4 |
   | 32nd St              |
   | 24th St        1 3/4 |
   | Jct 17             2 |
   +----------------------+

   the numbers are:  17  24  32  2  1/4  (1 3/4)

                          24 - 2                  22
   the math is:  ----------------------------- = ---- = Pi
                 (17 + 32) x ((1/4) / (1 3/4))     7

   more math is:

   observe...
      1 3/4 = 7/4
      17 + 32 = 49
      (1/4) / (1 3/4) = (1/4) / (7/4) = (1/4) x (4/7) = 1/7
      49 x (1/7) = 49/7 = 7

   observe decimal number usage...
      .25 / 1.75 = .14285714
      49 x .14285714 = 6.99999986
