(9615.36 +1247.18) - (2435.72 +1937.92) = ?

Answer

To solve the expression \((9615.36 + 1247.18) - (2435.72 + 1937.92)\) using approximation, we will follow these steps:

### Step 1: Approximate the numbers
We will round each number to the nearest whole number:
- \(9615.36 \approx 9615\)
- \(1247.18 \approx 1247\)
- \(2435.72 \approx 2436\)
- \(1937.92 \approx 1938\)

### Step 2: Rewrite the expression
Now we can rewrite the expression using the approximated values:
\[ (9615 + 1247) - (2436 + 1938) \]

### Step 3: Add the numbers in the first bracket
Now, we add the numbers in the first bracket:
\[ 9615 + 1247 = 10862 \]

### Step 4: Add the numbers in the second bracket
Next, we add the numbers in the second bracket:
\[ 2436 + 1938 = 4374 \]

### Step 5: Subtract the second sum from the first sum
Now, we subtract the result of the second bracket from the first:
\[ 10862 - 4374 = 6488 \]

### Final Answer
Thus, the approximate value of \((9615.36 + 1247.18) - (2435.72 + 1937.92)\) is:
\[ \boxed{6488} \]
