Now, let’s match each answer to the color key:

Color Key:
- 101–150 = YELLOW
- 151–200 = ORANGE
- 201–250 = PINK
- 251–300 = BLUE
- 301–350 = PURPLE
- 351–400 = WHITE

Let’s assign colors based on answers:

1. 108 → YELLOW
2. 422 → too big? Wait — 422 is over 400? But max in key is 400=WHITE. Let me check if I made a mistake.

Wait — looking back at problem #2: 551 - 129.

Let me recalculate that:

551 - 129:

→ 551 - 100 = 451
→ 451 - 20 = 431
→ 431 - 9 = 422 → yes, correct.

But 422 is above 400. The key only goes up to 400=WHITE. That can’t be right. Maybe I misread the problem?

Looking again at the image description — perhaps some problems are written vertically? For example, “551 -129” might mean 551 minus 129, which is 422 — but that’s outside the range.

Wait — maybe it’s 551 - 129 = 422, but perhaps the worksheet has a typo? Or maybe I should double-check all calculations.

Actually, let’s recheck problem #2: 551 - 129.

Do it column-wise:

551
- 129
------
Start from right: 1 - 9 → borrow → 11 - 9 = 2
Middle: 4 (after borrow) - 2 = 2
Left: 5 - 1 = 4 → so 422. Correct.

But 422 > 400 — not in key. Hmm.

Wait — look at problem #9: 774 - 627 = 147 → that’s fine.

Problem #10: 593 - 440 = 153 → fine.

Problem #11: 589 - 390 = 199 → fine.

Problem #2: 551 - 129 = 422 — this must be an error? Or perhaps I misread the numbers.

Wait — in the original image description, it says:

“551
-129”

That’s definitely 551 - 129 = 422.

But 422 is not in any color range. The highest is 351-400=WHITE.

This suggests either:

- There’s a typo in the worksheet, or
- I misread the number.

Wait — let me check another one: problem #1: 471 - 363 = 108 → correct.

Problem #3: 649 - 306 = 343 → correct.

Problem #4: 719 - 386 = 333 → correct.

Problem #5: 942 - 586 = 356 → correct.

Problem #6: 570 - 316 = 254 → correct.

Problem #7: 648 - 501 = 147 → correct.

Problem #8: 822 - 545 = 277 → correct.

Problem #9: 774 - 627 = 147 → correct.

Problem #10: 593 - 440 = 153 → correct.

Problem #11: 589 - 390 = 199 → correct.

Problem #12: 753 - 618 = 135 → correct.

Problem #13: 582 - 352 = 230 → correct.

Problem #14: 439 - 183 = 256 → correct.

Problem #15: 663 - 555 = 108 → correct.

Problem #16: 992 - 774 = 218 → correct.

Problem #17: 592 - 268 = 324 → correct.

Problem #18: 487 - 254 = 233 → correct.

Problem #19: 896 - 762 = 134 → correct.

Problem #20: 468 - 349 = 119 → correct.

Problem #21: 591 - 283 = 308 → correct.

Problem #22: 884 - 538 = 346 → correct.

Problem #23: 753 - 412 = 341 → correct.

Problem #24: 593 - 286 = 307 → correct.

Problem #25: 891 - 643 = 248 → correct.

Problem #26: 723 - 591 = 132 → correct.

Problem #27: 793 - 453 = 340 → correct.

Problem #28: 723 - 405 = 318 → correct.

Problem #29: 632 - 311 = 321 → correct.

Problem #30: 642 - 325 = 317 → correct.

Problem #31: 584 - 439 = 145 → correct.

Problem #32: 672 - 408 = 264 → correct.

Problem #33: 727 - 459 = 268 → correct.

Problem #34: 853 - 592 = 261 → correct.

Problem #35: 691 - 403 = 288 → correct.

Problem #36: 722 - 430 = 292 → correct.

Problem #37: 823 - 526 = 297 → correct.

Problem #38: 935 - 654 = 281 → correct.

All calculations seem correct. But problem #2 gives 422, which is outside the color key.

Wait — perhaps the problem is written as "551 - 129" but meant to be "551 - 429"? No, that would be 122.

Or maybe it's "551 - 129" but the answer is supposed to be colored as WHITE since it's close? But 422 > 400.

Alternatively, perhaps I misread the problem. Let me look back at the user's input:

In the text: "551
-129"

Yes, that's 551 - 129 = 422.

But in the color key, the highest is 351-400=WHITE. So 422 doesn't fit.

This might be an error in the worksheet. However, for the sake of completing the task, perhaps we should assume that any answer over 400 is also WHITE? Or maybe it's a typo and it's supposed to be 551 - 429 = 122? But that's speculation.

Another possibility: perhaps "551 -129" is meant to be read as 551 minus 129, but in the context of the worksheet, maybe it's part of a larger number? Unlikely.

Given that all other answers fall within 101-400, and only this one is 422, I suspect there might be a typo in the problem. But since I have to provide an answer, I'll note that 422 is outside the range, but for coloring purposes, perhaps it should be WHITE as the closest.

However, let's double-check the calculation once more:

551 - 129:

551
-129
----
1 - 9: borrow, 11-9=2
5 becomes 4, 4-2=2
5-1=4 → 422. Yes.

Perhaps the problem is 551 - 129 = 422, and the color key is incomplete, but in practice, students might color it white.

To proceed, I'll list all answers with their colors, and for 422, I'll put WHITE as it's the highest category.

So final answers with colors:

1. 108 → YELLOW
2. 422 → WHITE (assuming overflow)
3. 343 → PURPLE
4. 333 → PURPLE
5. 356 → WHITE
6. 254 → PINK
7. 147 → YELLOW
8. 277 → BLUE
9. 147 → YELLOW
10. 153 → ORANGE
11. 199 → ORANGE
12. 135 → YELLOW
13. 230 → PINK
14. 256 → PINK
15. 108 → YELLOW
16. 218 → PINK
17. 324 → PURPLE
18. 233 → PINK
19. 134 → YELLOW
20. 119 → YELLOW
21. 308 → PURPLE
22. 346 → PURPLE
23. 341 → PURPLE
24. 307 → PURPLE
25. 248 → PINK
26. 132 → YELLOW
27. 340 → PURPLE
28. 318 → PURPLE
29. 321 → PURPLE
30. 317 → PURPLE
31. 145 → YELLOW
32. 264 → BLUE
33. 268 → BLUE
34. 261 → BLUE
35. 288 → BLUE
36. 292 → BLUE
37. 297 → BLUE
38. 281 → BLUE

Note: Problem #2 (422) is assigned WHITE as it exceeds 400, though technically not in key.

Final Answer: All problems solved; colors assigned as above. For coloring, use the color key with the calculated answers. If a result is over 400, consider it WHITE.
