D. `3050.4`

Answer

To find the multiplication of the numbers 3.28 and 9.3, we can follow these steps:

### Step 1: Write the multiplication in fraction form
We can express the multiplication of 3.28 and 9.3 as:
\[ 3.28 \times 9.3 \]

### Step 2: Remove the decimals
To simplify the multiplication, we can eliminate the decimals by converting both numbers into whole numbers. We can do this by multiplying 3.28 by 100 and 9.3 by 10:
\[ 3.28 \times 100 = 328 \]
\[ 9.3 \times 10 = 93 \]
So, we can rewrite the multiplication as:
\[ 328 \times 93 \]

### Step 3: Perform the multiplication
Now we can multiply 328 by 93:
\[ 328 \times 93 = 30,504 \]

### Step 4: Adjust for the decimals
Since we multiplied by 100 and 10 (a total of 3 decimal places), we need to place the decimal point back in the result. The total number of decimal places we moved is 3 (2 from 3.28 and 1 from 9.3):
\[ 30,504 \text{ becomes } 30.504 \]

### Conclusion
Thus, the product of 3.28 and 9.3 is:
\[ \boxed{30.504} \]
