C. 0.36
D. `1/36` %

Answer

To find out what percent of 15 hours is 18 seconds, we can follow these steps:

### Step 1: Convert hours to seconds
First, we need to convert 15 hours into seconds. We know that:
1 hour = 3600 seconds.

So, to convert 15 hours to seconds:
\[ 15 \text{ hours} = 15 \times 3600 \text{ seconds} \]
\[ 15 \text{ hours} = 54000 \text{ seconds} \]

### Step 2: Set up the percentage equation
Now, we need to find out what percent 18 seconds is of 54000 seconds. We can set up the equation as follows:
\[ \text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100 \]
Here, the part is 18 seconds and the whole is 54000 seconds. Therefore, we can write:
\[ \text{Percentage} = \left( \frac{18}{54000} \right) \times 100 \]

### Step 3: Calculate the percentage
Now, we will calculate the percentage:
\[ \text{Percentage} = \left( \frac{18}{54000} \right) \times 100 \]
\[ \text{Percentage} = \left( \frac{18 \times 100}{54000} \right) \]
\[ \text{Percentage} = \frac{1800}{54000} \]
\[ \text{Percentage} = \frac{1}{30} \]
\[ \text{Percentage} \approx 0.0333 \times 100 \approx 3.33\% \]

### Final Answer
Thus, 18 seconds is approximately **3.33%** of 15 hours.
