Estimate the quotient by rounding both numbers to make the division easier: \(170{,}715 \div 57\)
Correct Answer
3,000
Explanation
Round both up: \(170{,}715 \approx 180{,}000\) and \(57 \approx 60\). Then use the trailing-zeros shortcut: \(180{,}000 \div 60 = 18{,}000 \div 6 = 3{,}000\). (Exact answer: 2,995.)
