What do you get when you multiply 416 by 7 with proper placeholders?

1. A. 2,912

2. B. 29,120

3. C. 30,000

4. D. 25,000

The correct answer is: B. 29,120

To find the product of 416 by 7, we need to perform the multiplication straightforwardly. When you multiply 416 by 7, you align the numbers correctly and perform the calculation step by step. First, multiply the units place: 6 multiplied by 7 gives you 42. You write down the 2 and carry over the 4. Next, multiply the tens place: 1 multiplied by 7 gives you 7, and adding the carry over (4) results in 11. You write down the 1 and carry over the 1. Lastly, multiply the hundreds place: 4 multiplied by 7 gives you 28, and adding the carry over (1) results in 29. Putting together the results from the units, tens, and hundreds places gives you 2,912. This is the correct calculation, confirming that 416 multiplied by 7 yields the answer 2,912, aligning with the appropriate use of placeholders during the multiplication process. The other answers do not align with the calculation. Choices that suggest larger numbers, like 29,120 or others like 30,000 and 25,000, are too high and reflect an incorrect understanding of the place value involved
