To find \( h'(3) \) where \( h(x) = \frac{f(x)}{g(x)} \), we use the **quotient rule** for differentiation, which states:

\[
h'(x) = \frac{f'(x)g(x) - f(x)g'(x)}{[g(x)]^2}
\]

### Given values:
- \( f(3) = 2 \)
- \( f'(3) = -1 \)
- \( g(3) = 4 \)
- \( g'(3) = 5 \)

### Applying these values to \( h'(3) \):

\[
h'(3) = \frac{f'(3) \cdot g(3) - f(3) \cdot g'(3)}{[g(3)]^2}
\]

Substitute the values:

\[
h'(3) = \frac{(-1) \cdot 4 - 2 \cdot 5}{4^2}
\]

Calculate each term:

1. \( (-1) \cdot 4 = -4 \)
2. \( 2 \cdot 5 = 10 \)
3. \( 4^2 = 16 \)

Now, substitute these into the expression:

\[
h'(3) = \frac{-4 - 10}{16} = \frac{-14}{16} = -\frac{7}{8}
\]

### Final Answer:
\[
h'(3) = -\frac{7}{8}
\]
