To use estimation to check an answer, first round the numbers involved in the calculation to make them simpler. Then perform the estimated calculation and compare the result to your original answer. If the estimate is significantly different from your original answer, it may indicate that there is an error or that the original answer needs to be re-evaluated. This method helps verify the reasonableness of the final answer.
A proper method for determining the reasonableness of a contractor and their proposed labor hour estimate involves comparing the estimate to historical data from similar projects, considering industry benchmarks, and assessing the contractor's experience and past performance. Additionally, conducting a detailed review of the work breakdown structure can help identify any discrepancies in the estimate. Engaging in discussions with the contractor to clarify assumptions and methodologies used in their estimate is also beneficial. This multi-faceted approach ensures a comprehensive evaluation of the proposed labor hours.

Reasonableness means its fair
4 x 0.8 = 3.2
The reasonableness standard is a legal principle that requires actions or decisions to be justifiable, understandable, and rational based on the circumstances. It is often used in legal contexts to assess whether a person's conduct meets an objective standard of reasonableness.
It means to give the reason of something, (numbers,sums,differences, and problems.)
Suppose at some point in your life you wanted to know the answer of 29 divided by 14. If you can estimate in your head that 30 divided by 15 is 2, you would expect the answer to be somewhere around two. Since 14 is a little less than half, you would expect the answer to be a little bit more than two. The actual answer of 29/14 is 2.07.
The reasonableness of conduct is a legal standard used to evaluate if someone acted in a way that an ordinary, prudent person would in similar circumstances. In a sentence, you could say "The court determined that the reasonableness of conduct in this case was questionable due to the lack of care taken by the defendant."
