| Problem | Number | Rounded to Nearest 10 | Correct Choice |
|--------|--------|------------------------|----------------|
| 1 | 886 | 890 | B |
| 2 | 132 | 130 | A |
| 3 | 274 | 270 | B |
| 4 | 982 | 980 | C |
| 5 | 165 | 170 | B |
| 6 | 460 | 460 | A |
| 7 | 649 | 650 | B |
| 8 | 832 | 830 | C |
> ⚠️ Note: In both sheets, the first problem is already marked as 830 (which seems to be an error — it should be 826 rounded to 830, but the original number is listed as 826, so the answer is correct). But in the left sheet, the first problem says "Round 886", and the answer given is 890, which is correct.
So all answers are consistent.

- We look at the ones digit.
- If it’s 5 or more, we round up (add 10).
- If it’s less than 5, we round down (keep the tens digit same).
- Numbers ending in 0 are already multiples of 10.
✔ All solutions follow this rule.
