Answer

To solve the problem \( \frac{1}{0.04} \), we can follow these steps:

### Step 1: Convert the decimal to a fraction
The decimal \( 0.04 \) can be expressed as a fraction. Since \( 0.04 \) is equivalent to \( \frac{4}{100} \), we can rewrite the expression:

\[ \frac{1}{0.04} = \frac{1}{\frac{4}{100}} \]

### Step 2: Simplify the fraction
When dividing by a fraction, we can multiply by its reciprocal. Therefore, we can rewrite the expression as:

\[ \frac{1}{\frac{4}{100}} = 1 \times \frac{100}{4} = \frac{100}{4} \]

### Step 3: Perform the division
Now we need to divide \( 100 \) by \( 4 \):

\[ \frac{100}{4} = 25 \]

### Conclusion
Thus, \( \frac{1}{0.04} = 25 \).

### Final Answer
The answer is \( 25 \).
