Lenore rounds each factor to the nearest ten to estimate the product of 51*37 as 1,500. is lenore estimate reasonable? explain

No

Step-by-step explanation:

It is quite reasonable to round to the nearest ten to estimate an answer.

However, Lenore made a mistake in the rounding.

Rounded to the nearest ten, 37 ≈40. So,

51 * 37 ≈ 50 * 40 = 2000.

Her estimate of 1500 was wrong.

Ignore it because the answer to 51*37 is 1,887 not 1,500 which means that they are reducing it not rounding it.
