Pretend you are completing the following calculation:

41001 - 156 - 100.5 = 

Using rules related to significant figures, your answer should be rounded to:

Question 3 options:

The hundreds place: (example: 400)


The tens place: (example: 440)


The ones place: (example: 444)


The tenths place: (example: 444.4)


The hundredths place: (example: 444.44)


The thousandths place: (example: 444.444)

To solve the calculation \( 41001 - 156 - 100.5 \) and round it according to significant figures, we'll first break down the process.

### Step 1: Perform the calculation

\[
41001 - 156 - 100.5 = 40744.5
\]

### Step 2: Apply the rules of significant figures

For subtraction, the result should be rounded based on the decimal place of the least precise number in the calculation. Here's what we have:

- \( 41001 \): No decimal places (precision in the ones place)
- \( 156 \): No decimal places (precision in the ones place)
- \( 100.5 \): One decimal place (precision in the tenths place)

The least precise number is \( 41001 \) and \( 156 \), which both have no decimal places (precision in the ones place).

### Step 3: Round the result to the same precision

Since the least precise number is in the ones place, we round \( 40744.5 \) to the ones place. The final answer is:

\[
40745
\]

### Conclusion: The correct rounding is to **the ones place**.
