Estimate the product of by rounding each number to the nearest 10.
- Since the specific numbers weren't provided in your question, I'll give you a principle based on rounding. If you were rounding numbers like 15,000 and 16,000 to the nearest ten (which they already are), you'd multiply those numbers.
- 15,000 x 16,000 = 240,000, which is estimating to encourage rounding even further. It seems you may need the specific numbers to apply.
- Answer: (This is a conceptual response since the exact numbers were not provided.)
-
