Multiplying by 9 (A) Answers worksheet with completed multiplication problems and solutions.

To solve this worksheet, we need to calculate the product for each multiplication problem. The worksheet is titled "Multiplying by 9," so every problem involves multiplying a number by 9.

Here is the step-by-step verification of the answers shown in red on the sheet. I will go row by row, from left to right.

Row 1:
1. $12 \times 9 = 108$ (Correct)
2. $10 \times 9 = 90$ (Correct)
3. $5 \times 9 = 45$ (Correct)
4. $8 \times 9 = 72$ (Correct)
5. $4 \times 9 = 36$ (Correct)
6. $3 \times 9 = 27$ (Correct)
7. $6 \times 9 = 54$ (Correct)
8. $11 \times 9 = 99$ (Correct)
9. $9 \times 9 = 81$ (Correct)
10. $2 \times 9 = 18$ (Correct)

Row 2:
1. $7 \times 9 = 63$ (Correct)
2. $1 \times 9 = 9$ (Correct)
3. $2 \times 9 = 18$ (Correct)
4. $9 \times 9 = 81$ (Correct)
5. $5 \times 9 = 45$ (Correct)
6. $3 \times 9 = 27$ (Correct)
7. $7 \times 9 = 63$ (Correct)
8. $12 \times 9 = 108$ (Correct)
9. $4 \times 9 = 36$ (Correct)
*(Note: There are only 9 problems in this row visually, but let's check the layout carefully. Ah, looking at the image, Row 2 has 9 items. Wait, let me recount.
Row 1: 10 items.
Row 2: 9 items? No, let's look closer.
Row 2 starts with $7 \times 9$. Ends with $4 \times 9$. Let's list them:
$7\times9=63$, $1\times9=9$, $2\times9=18$, $9\times9=81$, $5\times9=45$, $3\times9=27$, $7\times9=63$, $12\times9=108$, $4\times9=36$. That is 9 items. But usually these grids are uniform. Let me re-examine the image structure.
Actually, looking at the spacing, Row 2 seems to have 9 columns filled. Let's look at Row 3.
Row 3: $9\times8$, $9\times1$, $9\times10$, $9\times6$, $9\times10$, $9\times1$, $9\times8$, $9\times9$, $9\times2$, $9\times7$. That's 10 items.
Let's re-read Row 2. It looks like there might be a missing column or I miscounted.
Let's look at the headers. There are no column headers.
Let's just verify every single visible equation and its red answer.

Re-evaluating Row 2:
The problems are:
$7 \times 9 = 63$
$1 \times 9 = 9$
$2 \times 9 = 18$
$9 \times 9 = 81$
$5 \times 9 = 45$
$3 \times 9 = 27$
$7 \times 9 = 63$
$12 \times 9 = 108$
$4 \times 9 = 36$
All these calculations are correct.

Row 3:
1. $9 \times 8 = 72$ (Correct)
2. $9 \times 1 = 9$ (Correct)
3. $9 \times 10 = 90$ (Correct)
4. $9 \times 6 = 54$ (Correct)
5. $9 \times 10 = 90$ (Correct)
6. $9 \times 1 = 9$ (Correct)
7. $9 \times 8 = 72$ (Correct)
8. $9 \times 9 = 81$ -> Wait, the image shows $9 \times 9$? No, looking closely at the 8th item in Row 3: It is $9 \times 9$? No, it says $9 \times 9$ above a line? Let me zoom in.
- Item 8 in Row 3 is: Top number 9, bottom number $\times 9$? No, it looks like $9 \times 9$ is not right. Let's look at the answer. The answer is 54. So the problem must be $6 \times 9$ or $9 \times 6$. The top number is 9. The bottom multiplier is... it looks like a 6? Or is it $9 \times 6$?
- Actually, let's look at the pattern. The multipliers (bottom numbers) in Row 3 are: 8, 1, 10, 6, 10, 1, 8, 9, 2, 7.
- If the 8th problem is $9 \times 9$, the answer should be 81. The answer written is 54. This would be an error if the problem is $9 \times 9$.
- Let me look really closely at the 8th problem in Row 3. The top digit is 9. The bottom digit is $\times 9$? Or is it $\times 6$? The loop of the 6 is at the bottom. The loop of the 9 is at the top. The digit under the 9 looks like a 6. Yes, it is a 6. So $9 \times 6 = 54$. This is Correct.
- Let's check the 9th problem: $9 \times 2 = 18$. Correct.
- Let's check the 10th problem: $9 \times 7 = 63$. Correct.

Row 4:
1. $9 \times 9 = 81$ -> Answer shown is 27. Wait.
- Let's look at the first problem in Row 4. Top: 9. Bottom: $\times 9$. Answer: 27?
- $9 \times 9 = 81$. $3 \times 9 = 27$.
- Let me look at the top number again. Is it a 3? It looks like a 9.
- Let's look at the second problem in Row 4: $9 \times 7$. Answer 63. Correct.
- Third: $9 \times 11$. Answer 99. Correct.
- Fourth: $9 \times 4$. Answer 36. Correct.
- Fifth: $9 \times 6$. Answer 54. Correct.
- Sixth: $9 \times 2$. Answer 18. Correct.
- Seventh: $9 \times 1$. Answer 9. Correct.
- Eighth: $9 \times 3$. Answer 27. Correct.
- Ninth: $9 \times 9$. Answer 81. Correct.
- Tenth: $9 \times 5$. Answer 45. Correct.

Let's re-examine the first problem in Row 4.
Top number: Looks like a 3? No, it has a loop at the top. It looks like a 9.
Bottom number: $\times 9$.
Answer: 27.
If the answer is 27, the problem should be $3 \times 9$.
Looking very closely at the top digit of the first problem in Row 4... it actually looks like a 3 that is written poorly, or perhaps a 9 where the answer key is wrong?
However, looking at the other 9s on the page, they have a distinct straight tail. The digit in the first spot of Row 4 has a curved tail. It is likely a 3.
Let's assume it is $3 \times 9 = 27$. This matches the answer.

Let's re-examine the eighth problem in Row 4.
Top: 9. Bottom: $\times 3$. Answer: 27. Correct ($9 \times 3 = 27$).

Let's re-examine the ninth problem in Row 4.
Top: 9. Bottom: $\times 9$. Answer: 81. Correct.

So, assuming the first digit in Row 4 is a 3, all answers in Row 4 are correct.

Row 5:
1. $4 \times 9 = 36$ (Correct)
2. $9 \times 9 = 81$ -> Answer shown is 9.
- Let's look closely. Top: 9. Bottom: $\times 9$? No, the bottom number is 1. It is $9 \times 1$.
- Answer: 9. Correct.
3. $9 \times 2 = 18$ (Correct)
4. $9 \times 8 = 72$ (Correct)
5. $9 \times 3 = 27$ (Correct)
6. $9 \times 11 = 99$ (Correct)
7. $9 \times 7 = 63$ (Correct)
8. $9 \times 10 = 90$ (Correct)
9. $9 \times 12 = 108$ (Correct)
10. $9 \times 6 = 54$ (Correct)

Row 6:
1. $9 \times 1 = 9$ (Correct)
2. $9 \times 3 = 27$ (Correct)
3. $9 \times 2 = 18$ (Correct)
4. $9 \times 4 = 36$ (Correct)
5. $9 \times 5 = 45$ (Correct)
6. $9 \times 9 = 81$ (Correct)
7. $9 \times 6 = 54$ (Correct)
8. $9 \times 7 = 63$ (Correct)
9. $9 \times 10 = 90$ (Correct)
10. $9 \times 12 = 108$ (Correct)

Row 7:
1. $11 \times 9 = 99$ (Correct)
2. $9 \times 8 = 72$ (Correct)
3. $9 \times 4 = 36$ (Correct)
4. $9 \times 12 = 108$ (Correct)
5. $9 \times 7 = 63$ (Correct)
6. $9 \times 5 = 45$ (Correct)
7. $9 \times 9 = 81$ -> Wait. The problem is $9 \times 9$?
- Top: 9. Bottom: $\times 9$? No, bottom is $\times 1$? Or $\times 7$?
- Let's look at the answer: 99.
- If the answer is 99, the problem is $11 \times 9$.
- The top number is 9. The bottom number looks like a 9? No, it looks like an 11? No, single digit.
- Let's look at the 7th item in Row 7 again.
- Top: 9. Bottom: $\times 9$? Answer: 99? That would be wrong.
- Let's look at the digit again. It is $9 \times 11$? No, the bottom part is clearly a single digit '9' or '7' or '1'.
- Wait, let's look at the previous column (6th item). $9 \times 5 = 45$.
- Next column (8th item). $9 \times 1 = 9$? Answer 72? No.
- Let's restart Row 7 carefully.
1. $11 \times 9 = 99$. (Top 11, Bottom 9). Correct.
2. $9 \times 8 = 72$. (Top 9, Bottom 8). Correct.
3. $9 \times 4 = 36$. (Top 9, Bottom 4). Correct.
4. $9 \times 12 = 108$. (Top 9, Bottom 12). Correct.
5. $9 \times 7 = 63$. (Top 9, Bottom 7). Correct.
6. $9 \times 5 = 45$. (Top 9, Bottom 5). Correct.
7. Problem: Top 9, Bottom 9? Answer 99.
- $9 \times 9 = 81$. The answer written is 99. This is Incorrect IF the problem is $9 \times 9$.
- Is the bottom number 11? It looks like a single digit. It looks like a 9.
- Is the top number 11? No, it's a 9.
- Let's look at the next one to see if I shifted columns.
8. Problem: Top 9, Bottom 1? Answer 72?
- $9 \times 1 = 9$. Answer is 72. This is definitely wrong.
- $9 \times 8 = 72$. So maybe the bottom number is 8? It looks like a 1.

Let's look at the whole row 7 again. Maybe I am misaligning the columns because of the varying widths of numbers (like 11 vs 9).

Let's trace from the right side of Row 7.
Last item (10th): $9 \times 9 = 81$. Top 9, Bottom 9. Answer 81. Correct.
9th item: $9 \times 8 = 72$? Top 9, Bottom 8? Answer 72? No, the answer is 72 under a problem that looks like $9 \times 8$?
Let's look at the 9th item from left in Row 7.
Top: 9. Bottom: 8? Answer: 72.
Wait, the image shows:
Col 7: $9 \times 9$? Answer 99.
Col 8: $9 \times 1$? Answer 72.
Col 9: $9 \times 8$? Answer 81.
Col 10: $9 \times 9$? Answer 81.

This row seems messy or I am misreading the digits. Let's look at the printed answers in red and reverse engineer the question to see if it matches the visual.

Row 7 Analysis:
1. $11 \times 9 = 99$. (Matches visual: Top 11, Bot 9). OK.
2. $9 \times 8 = 72$. (Matches visual: Top 9, Bot 8). OK.
3. $9 \times 4 = 36$. (Matches visual: Top 9, Bot 4). OK.
4. $9 \times 12 = 108$. (Matches visual: Top 9, Bot 12). OK.
5. $9 \times 7 = 63$. (Matches visual: Top 9, Bot 7). OK.
6. $9 \times 5 = 45$. (Matches visual: Top 9, Bot 5). OK.
7. Visual: Top 9, Bot 9. Answer: 99.
- Calculation: $9 \times 9 = 81$.
- Written Answer: 99.
- Discrepancy: The answer key says 99, but $9 \times 9$ is 81. Did I misread the bottom number? Could it be 11? It doesn't look like 11. It looks like a 9. Could the top number be 11? It looks like a 9.
- Let's look at the next one.
8. Visual: Top 9, Bot 1. Answer: 72.
- Calculation: $9 \times 1 = 9$.
- Written Answer: 72.
- Discrepancy: Huge error. $9 \times 8 = 72$. Does the bottom number look like an 8? It looks like a 1.
9. Visual: Top 9, Bot 8. Answer: 81.
- Calculation: $9 \times 8 = 72$.
- Written Answer: 81.
- Discrepancy: $9 \times 9 = 81$. Does the bottom number look like a 9? It looks like an 8.
10. Visual: Top 9, Bot 9. Answer: 81.
- Calculation: $9 \times 9 = 81$.
- Written Answer: 81.
- This one is correct.

It appears that in Row 7, columns 7, 8, and 9 might be shifted or misprinted in my reading. Let's look at the sequence of answers in Row 7:
99, 72, 36, 108, 63, 45, 99, 72, 81, 81.

Let's look at the questions again for 7, 8, 9, 10.
Q7: $9 \times ?$ -> Ans 99. Must be $11 \times 9$. The top number is 9. The bottom number is 9. This is likely an error in the worksheet key OR the bottom number is a poorly written 11? Unlikely.
Q8: $9 \times ?$ -> Ans 72. Must be $8 \times 9$. The bottom number looks like a 1.
Q9: $9 \times ?$ -> Ans 81. Must be $9 \times 9$. The bottom number looks like an 8.
Q10: $9 \times ?$ -> Ans 81. Must be $9 \times 9$. The bottom number looks like a 9.

Actually, looking at Q7, Q8, Q9, Q10 in Row 7:
Q7: Top 9, Bot 9. Ans 99. (Error: $9\times9=81$)
Q8: Top 9, Bot 1. Ans 72. (Error: $9\times1=9$)
Q9: Top 9, Bot 8. Ans 81. (Error: $9\times8=72$)
Q10: Top 9, Bot 9. Ans 81. (Correct)

Wait, let me look at the image source or context. This is "Math-Drills.com". These are usually auto-generated.
Is it possible I am misreading the numbers due to resolution?
Let's look at Q7 in Row 7 again. Top number: 9. Bottom number: 9. Answer: 99.
Let's look at Q8 in Row 7 again. Top number: 9. Bottom number: 1? Or 7? $9\times7=63$. Answer is 72.
Let's look at Q9 in Row 7 again. Top number: 9. Bottom number: 8? Answer 81.

There seems to be a significant cluster of errors or misreadings in Row 7. However, for the purpose of helping the student, I should provide the correct mathematical answers to the problems as they appear visually. If the visual is ambiguous, I will note the most likely interpretation.

BUT, looking at the entire sheet, almost every other answer is perfectly correct. It is highly probable that I am misinterpreting the blurry digits in Row 7, columns 7-9.
Let's try another hypothesis:
Maybe Q7 is $11 \times 9$? Top digit is 9. Maybe it's a 11 compressed? No.
Maybe Q8 is $8 \times 9$? Bottom digit is 1. Maybe it's an 8? An 8 has two loops. A 1 is a stick. It looks like a stick.
Maybe Q9 is $9 \times 9$? Bottom digit is 8. Maybe it's a 9? A 9 has a loop at top. An 8 has loops top and bottom. It looks like an 8.

Let's look at Row 8 to see if there are similar issues.

Row 8:
1. $3 \times 9 = 27$ (Correct)
2. $9 \times 9 = 81$ -> Answer shown 90.
- Problem: Top 9, Bot 9? Or Top 9, Bot 10?
- If Bot is 10, $9 \times 10 = 90$. The bottom digit looks like a 9? Or a 10? It looks like a single digit 9.
- If it is $9 \times 9$, answer is 81. Key says 90.
- Let's look at the next one.
3. $6 \times 9 = 54$ (Correct)
4. $9 \times 2 = 18$ (Correct)
5. $9 \times 12 = 108$ (Correct)
6. $9 \times 5 = 45$ (Correct)
7. $9 \times 1 = 9$ (Correct)
8. $9 \times 9 = 81$ -> Answer shown 99.
- Problem: Top 9, Bot 9. Answer 99. Error? $9 \times 9 = 81$.
9. $9 \times 4 = 36$ (Correct)
10. $9 \times 2 = 18$ (Correct)

So in Row 8, Item 2 ($9\times9$?) has answer 90. Item 8 ($9\times9$?) has answer 99.
This suggests that some of the "9" multipliers might actually be "10" or "11"?
- If Item 2 in Row 8 is $9 \times 10$, answer 90 is correct. Does the bottom digit look like 10? It looks like a 9.
- If Item 8 in Row 8 is $9 \times 11$, answer 99 is correct. Does the bottom digit look like 11? It looks like a 9.

Conclusion on Worksheet Accuracy:
The worksheet contains several instances where the printed answer (in red) does not match the standard multiplication of the visible digits. Specifically, where the answer is 90, the multiplier was likely 10. Where the answer is 99, the multiplier was likely 11. Where the answer is 72, the multiplier was likely 8.
However, visually, the digits often look like 9, 1, etc.
Given the user wants me to "Solve the problem accurately", I should provide the correct mathematical products for the expressions as written. If the expression is $9 \times 9$, the answer is 81, even if the key says 99.

BUT, looking at the prompt "Solve the problem accurately", and the fact that this is an "Answers" sheet, the user might just want the text extracted or verified.
Actually, the user uploaded an image of a completed worksheet with answers in red. The request is "Solve the problem accurately". This implies I should act as the solver. Since the answers are already there, I am essentially verifying them.
If I find discrepancies, I should point out the correct math.

Let's do a final pass of the potentially problematic ones to ensure I'm not crazy.
Row 7, Col 7: $9 \times 9$. Red Answer: 99. Correct Math: 81.
Row 7, Col 8: $9 \times 1$. Red Answer: 72. Correct Math: 9.
Row 7, Col 9: $9 \times 8$. Red Answer: 81. Correct Math: 72.
Row 8, Col 2: $9 \times 9$. Red Answer: 90. Correct Math: 81.
Row 8, Col 8: $9 \times 9$. Red Answer: 99. Correct Math: 81.

It is highly likely that the font for '11' looks like '9' or '1' in some places, or the worksheet generator has bugs.
However, for a student, the most helpful thing is the correct multiplication fact.

I will list the solutions for every problem on the sheet, row by row. I will assume the visual digits are the intended problem. If a digit is ambiguous (like looking like a 9 but acting like an 11), I will provide the answer based on the visual appearance but add a note if necessary. Actually, simpler is better. I will just provide the correct product for the visible numbers.

Let's refine the list.
