Estimate the product. Round each factor to the nearest ten, then multiply.

To estimate the product of 68 × 49 by rounding each factor to the nearest ten:

1. Round 68 to the nearest ten, which is 70.
2. Round 49 to the nearest ten, which is 50.

Now, multiply the rounded figures:

70 × 50 = 3500

So, the product is approximately 3500.

This method gives us a quick way to estimate the actual product without calculating it precisely. Let me know if you have another question!
