Question

The result of which expression will best estimate the actual product of −453×−6756?

A. 3,000,000
B. 4,000,000
C. 5,000,000
D. 6,000,000

Answer 1

The best estimate for the product of −453 and −6756, after rounding to one significant figure, is 3,500,000, which suggests that 3,000,000 (Option A) is the closest estimate.

Step-by-step explanation:

To find which expression will best estimate the product of −453×−6756, we can round these numbers to one significant figure and multiply them together. Therefore, −453 rounds to −500 and −6756 rounds to −7000. The product of these estimates is 500×7000, which equals 3,500,000. The closest answer choice to our estimate is 3,000,000 (Option A).
