Row 1:

- 24: 2 + 4 = 6 → 6 ÷ 3 = 2 → YES
- 199: 1 + 9 + 9 = 19 → 19 ÷ 3 = 6 remainder 1 → NO
- 132: 1 + 3 + 2 = 6 → 6 ÷ 3 = 2 → YES
- 133: 1 + 3 + 3 = 7 → 7 ÷ 3 = 2 remainder 1 → NO

Row 2:

- 175: 1 + 7 + 5 = 13 → 13 ÷ 3 = 4 remainder 1 → NO
- 312: 3 + 1 + 2 = 6 → 6 ÷ 3 = 2 → YES
- 77: 7 + 7 = 14 → 14 ÷ 3 = 4 remainder 2 → NO
- 180: 1 + 8 + 0 = 9 → 9 ÷ 3 = 3 → YES

Row 3:

- 98: 9 + 8 = 17 → 17 ÷ 3 = 5 remainder 2 → NO
- 750: 7 + 5 + 0 = 12 → 12 ÷ 3 = 4 → YES
- 256: 2 + 5 + 6 = 13 → 13 ÷ 3 = 4 remainder 1 → NO
- 198: 1 + 9 + 8 = 18 → 18 ÷ 3 = 6 → YES

Row 4:

- 852: 8 + 5 + 2 = 15 → 15 ÷ 3 = 5 → YES
- 200: 2 + 0 + 0 = 2 → 2 ÷ 3 = 0 remainder 2 → NO
- 351: 3 + 5 + 1 = 9 → 9 ÷ 3 = 3 → YES
