Answer:

sample answer: Sari had a good estimate for the problem. But she was not correct in saying that her answer was slightly greater than the actual answer. The rounded dividend, 120, is slightly less than 120.76, and the rounded divisor, 10, is slightly greater than 9.9, so the estimate would be less than the actual quotient.

Answer:

Yes, her estimate is greater than the actual answer. 120.78/9.9 = 12.2. Since 12.2 (the actual answer) is greater than her estimate of 12, she is correct.
