Answer
Rosie made mistakes in borrowing and aligning the digits, leading to an incorrect final answer of 19,676.
Solution
To analyze Rosie's workings and identify any mistakes, we first need to perform the subtraction \( 45,541 - 25,865 \) step by step.
### Step 1: Perform the Subtraction
Let's break down the subtraction:
```
45,541
- 25,865
__________
```
### Step 2: Subtract Digit by Digit
1. **Units Place**: \( 1 - 5 \)
- We cannot subtract 5 from 1, so we need to borrow 1 from the tens place.
- The 4 in the tens place becomes 3, and the 1 becomes 11.
- Now, \( 11 - 5 = 6 \).
2. **Tens Place**: \( 3 - 6 \)
- Again, we cannot subtract 6 from 3, so we need to borrow 1 from the hundreds place.
- The 5 in the hundreds place becomes 4, and the 3 becomes 13.
- Now, \( 13 - 6 = 7 \).
3. **Hundreds Place**: \( 4 - 8 \)
- We cannot subtract 8 from 4, so we need to borrow 1 from the thousands place.
- The 5 in the thousands place becomes 4, and the 4 becomes 14.
- Now, \( 14 - 8 = 6 \).
4. **Thousands Place**: \( 4 - 5 \)
- We cannot subtract 5 from 4, so we need to borrow 1 from the ten-thousands place.
- The 4 in the ten-thousands place becomes 3, and the 4 becomes 14.
- Now, \( 14 - 5 = 9 \).
5. **Ten-Thousands Place**: \( 3 - 2 = 1 \).
### Step 3: Combine the Results
Putting it all together, we have:
```
45,541
- 25,865
__________
19,676
```
### Step 4: Analyze Rosie's Workings
Now, let's analyze the table provided in Rosie's workings:
```
2 & 5 & 8 & 6 & 5
4 & 5 & 5 & 4 & 1
2 & 0 & 3 & 2 & 4
```
This table does not seem to correspond to the subtraction process we just performed. It appears to be a collection of numbers that do not relate to the subtraction of \( 45,541 - 25,865 \).
### Mistakes Identified
1. **Incorrect Borrowing**: If Rosie attempted to borrow incorrectly, it could lead to wrong digits in the final answer.
2. **Misalignment of Numbers**: The numbers in the table do not represent the digits involved in the subtraction, indicating a misunderstanding of the subtraction process.
3. **Final Result**: If Rosie arrived at a different final result, it would be due to the above mistakes.
### Conclusion
Rosie's workings do not reflect the correct process for subtracting \( 45,541 - 25,865 \). The correct answer is \( 19,676 \), and the mistakes likely stem from incorrect borrowing and misalignment of the digits.
