The correct Answer is:
To solve the equation \( 640.93 - ? + 874.95 = 590.92 \) and find the approximate value of the question mark (?), we can follow these steps: ### Step 1: Approximate the numbers We will round the numbers to the nearest whole number for simplicity: - \( 640.93 \) approximates to \( 641 \) - \( 874.95 \) approximates to \( 875 \) - \( 590.92 \) approximates to \( 591 \) ### Step 2: Rewrite the equation Now, we can rewrite the equation using the approximated values: \[ 641 - ? + 875 = 591 \] ### Step 3: Combine the known values Next, we can combine the known values on the left side: \[ (641 + 875) - ? = 591 \] Calculating \( 641 + 875 \): \[ 641 + 875 = 1516 \] So the equation becomes: \[ 1516 - ? = 591 \] ### Step 4: Isolate the question mark To find the value of ?, we can rearrange the equation: \[ ? = 1516 - 591 \] ### Step 5: Calculate the difference Now, we calculate \( 1516 - 591 \): \[ 1516 - 591 = 925 \] ### Conclusion Thus, the approximate value that will come in place of the question mark (?) is: \[ ? \approx 925 \]
