Estimate the product 67 × 89 by rounding to the nearest ten.

Explanation:
Rounding to the nearest ten simplifies multiplication by turning each number into a nearby ten. Round 67 to 70 and 89 to 90. Multiply the rounded numbers: 70 × 90 = 6,300. This gives a quick, reasonable estimate of the product, since the exact result (67 × 89) is a bit under 6,000, and using the rounded tens provides a consistent, easy-to-grasp approximation.
