- 39 x 37=2183

rounds to

reasonable

not reasonable

- 27 x 8= 2241

rounds to

reasonable

not reasonable

Not reasonable. Not reasonable.

Step-by-step explanation:

1) 39x37=2183 We've been given this product.

Since 37 and 39 is greater than 35, then we can Round it up both to 40. Estimating that product means 40*40=1600. 2183 exceeds 1443. So the first product we've been given it's not a reasonable one.

39x37=2183 (Given)

Rounding up

40 x 40 = 1600

39 x 37 = 1443

Not Reasonable. Because 2183 exceeds the estimation (1600).

2) 27 x 8 = 2241

Since 27 is near to 30, as well as 8 is to 10. Let's round them both up:

30* 10=300

27 x 8 =216

Not Reasonable. Because 2241 exceeds the estimation (300).
