The answer is 2,800. To estimate the product of 2 numbers, you round to the nearest ten or hundred. In this case, you would round 73 to 70, and 403 to 400, to make it easy to multiply. 70 x 400 = 2,800
25x80 < 28x87 < 30x90 --> 2000 < 28x87 < 2700?
3 x 29 = 87
The closest estimate for the product of 2 x 19 x 5 equals 200.
13 x 31 = 403
To estimate the product of 87 times 403, you can round both numbers to the nearest tens or hundreds. Rounding 87 to 90 and 403 to 400, you get 90 x 400 = 36,000. This is a rough estimate of the product of 87 times 403.

The best estimate is the true value.
13 x 31 equals 403. This is calculated by multiplying 13 by 31, which results in the product 403.
25x80 < 28x87 < 30x90 --> 2000 < 28x87 < 2700?
87 x 64 = 5568
(13) x (-31) = -403
3 x 29 = 87
87 = 3 x 29
The closest estimate for the product of 2 x 19 x 5 equals 200.
13 x 31 = 403
No need to estimate. The true answer is 345
