Let's solve the expression step by step:

\[
30 + \frac{1}{4} - 14 + 20 + 3 + \frac{1}{5}
\]

First, combine the whole numbers:

\[
30 - 14 + 20 + 3 = 39
\]

Now, add the fractions:

\[
\frac{1}{4} + \frac{1}{5} = \frac{5}{20} + \frac{4}{20} = \frac{9}{20}
\]

Finally, combine the result:

\[
39 + \frac{9}{20} = 39.45
\]

So, the final answer is:

\[
39.45
\]
