You need to evaluate derivative of the given function `g(x)` , such that:

`g'(x) = ((f(x))/4)' => g'(x) = (f'(x))/4`

You need to evaluate derivative of the function `g(x)` at `x = 4` , such that:

`g'(4) = (f'(4))/4`

Since the problem provides the information that `f'(4) = 1` , you need to replace 1 for `f'(4)` , such that:

`g'(4) = 1/4`

Since the numerator is smaller than denominator `(1 < 4)` , the derivative of the function `g(x)` at `x = 4` can only be expressed as a proper fraction.

**Hence, evaluating g'(4), under the given conditions, yields that `g'(4)` is a proper fraction, `g'(4) = 1/4.` **
