D. 43345

Explanation

To solve the expression \( 7\left(\frac{1}{17}\right) \times 3485 + 9\left(\frac{1}{18}\right) \times 2430 \), we will break it down step by step.

### Step 1: Calculate \( 7\left(\frac{1}{17}\right) \times 3485 \)

First, we need to multiply \( 7 \) by \( \frac{1}{17} \):

\[ 7 \times \frac{1}{17} = \frac{7}{17} \]

Now, we multiply \( \frac{7}{17} \) by \( 3485 \):

\[ \frac{7}{17} \times 3485 = \frac{7 \times 3485}{17} \]

Calculating \( 7 \times 3485 \):

\[ 7 \times 3485 = 24395 \]

Now, divide \( 24395 \) by \( 17 \):

\[ \frac{24395}{17} = 1435 \]

### Step 2: Calculate \( 9\left(\frac{1}{18}\right) \times 2430 \)

Next, we multiply \( 9 \) by \( \frac{1}{18} \):

\[ 9 \times \frac{1}{18} = \frac{9}{18} = \frac{1}{2} \]

Now, we multiply \( \frac{1}{2} \) by \( 2430 \):

\[ \frac{1}{2} \times 2430 = \frac{2430}{2} = 1215 \]

### Step 3: Add the results from Step 1 and Step 2

Now we add the results from both calculations:

\[ 1435 + 1215 = 2650 \]

### Final Answer

Thus, the final answer is:

\[ \boxed{2650} \]
