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

The best estimate is the true value.
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
64 + 23 = 87 64 x 23 = 1472
To round to estimate the product of 38 x 2, you first round each number to a more manageable value. In this case, you can round 38 to 40 and 2 to 0. Then, multiply the rounded numbers together to get an estimate of the product. In this case, 40 x 0 = 0. So, the estimated product of 38 x 2 is 0.
