BARS::Fractions On Yavapai County Road 10 Near Prescott, Arizona

This road sign was found on eastbound Yavapai Country Road 10 a couple of miles west of Prescott, Arizona.

The road sign says...

   +----------------------------+
   | <- Rifle Range         1/4 |
   | <- Anytown Camp        1/2 |
   | <- Granite Basin Lake    4 |
   +----------------------------+
   the numbers are:  1/4   1/2   4

   that math is:  (1/2) / (1/4) = sqrt(4)

   observe...
      (1/2) / (1/4) = 1/2 * 4 = 4/2 = 2
      sqrt(4) = 2

   using / as a delimiter...

   the numbers become:  1  4  1  2  4

   the math is:   1 + 4 + 1 - 2 = 4
   
   more math:  1 + 1 + 2 = sqrt(4 * 4)

   [solve for 'n']  (n/2) / (n/4) = sqrt(4)
Update::2009.02.06

This BARS was updated after it was selected to be one of the BARS of the Week for week 4 of the spring 2009 semester.

   the numbers are:  1/4   1/2   4

   more math:  4^(1/2) = reciprocal(sqrt(1/4))

   observe...
      sqrt(1/4) = sqrt(1)/sqrt(4) = 1/2
      reciprocal(1/2) = 2/1 = 2
      4^(1/2) = sqrt(4) = 2

   [evaluate using a calculator]  1/2 / 1/4 = ______
