volume_mute
Use front-end rounding to estimate: \(42 \times 763\)
Correct Answer
28,000
Explanation
- \(42 \to 40\) (nearest ten)
- \(763 \to 800\) (nearest hundred)
Estimate: \(40 \times 800 = 32{,}000\). Wait — let me recheck: \(763\) rounds to \(800\) (tens digit is 6 ≥ 5). \(40 \times 800 = 32{,}000\).
