The estimated product of 45 and 24, rounded to the nearest ten before multiplying, is 1000.

Step-by-step explanation:

To estimate the product of 45 and 24, rounded to the nearest ten before multiplying, you round each number to the nearest ten. Rounding 45 to the nearest ten gives 50, and rounding 24 to the nearest ten gives 20. After rounding, you multiply these two rounded numbers: 50×20=1000. Therefore, the estimated product of 45 and 24, rounded to the nearest ten before multiplying, is 1000.This method provides a quick approximation of the product while simplifying the calculations. Option A) 1000 correctly represents this estimated product.
