### 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.

```   +----------------------------+
| <- 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 = ______
