The correct Answer is:
To solve the equation \( 52500 \div 7 + 64680 \div 6 = 19500 - ? \), we will follow these steps: ### Step 1: Calculate \( 52500 \div 7 \) \[ 52500 \div 7 = 7500 \] **Hint:** To divide, you can use long division or simply check how many times 7 fits into 52500. ### Step 2: Calculate \( 64680 \div 6 \) \[ 64680 \div 6 = 10780 \] **Hint:** Similar to the previous step, you can use long division or check how many times 6 fits into 64680. ### Step 3: Add the results from Step 1 and Step 2 \[ 7500 + 10780 = 18280 \] **Hint:** When adding, align the numbers by their place values (units, tens, hundreds, etc.) to avoid mistakes. ### Step 4: Set up the equation from the original problem Now we have: \[ 18280 = 19500 - ? \] **Hint:** This equation shows that the left side equals the right side minus the unknown value. ### Step 5: Rearrange the equation to solve for \( ? \) To find \( ? \), we can rearrange the equation: \[ ? = 19500 - 18280 \] **Hint:** To isolate the question mark, you need to move all other terms to the other side of the equation. ### Step 6: Calculate \( 19500 - 18280 \) \[ 19500 - 18280 = 1220 \] **Hint:** Subtract the smaller number from the larger number, aligning the digits correctly. ### Conclusion Thus, the value that comes in place of the question mark (?) is: \[ ? = 1220 \] ### Final Answer The answer is \( 1220 \). ---
