Correct pairs:
- 922 ÷ 28 ≈ 900 ÷ 30 (900/30 = 30; actual ≈ 32.9 — a reasonable estimate)
- 816 ÷ 52 ≈ 800 ÷ 50 (800/50 = 16; actual ≈ 15.7 — a good estimate)

The others change the scale too much (e.g., 1250÷25 vs 12÷2, 992÷52 vs 1000÷10, 2966÷69 vs 2000÷60) and are not reasonable compatible-number estimates.
