Correct Answer
(1) \(59 \times 334\),Estimate over 10,000
(2) \(74 \times 488\),Estimate over 10,000
(3) \(12 \times 456\),Estimate under 10,000
(4) \(99 \times 87\),Estimate under 10,000
Explanation
- \(59 \times 334 \approx 60 \times 300 = 18{,}000\) → over 10,000
- \(74 \times 488 \approx 70 \times 500 = 35{,}000\) → over 10,000
- \(12 \times 456 \approx 10 \times 500 = 5{,}000\) → under 10,000
- \(99 \times 87 \approx 100 \times 90 = 9{,}000\) → under 10,000
