Question

hello so your going to estimate then divide and check for reasonablenns

Answer 1

Answer:

$\begin{gathered} 21,000\div40=525 \\ 21,312\div36=592 \end{gathered}$

The answer 525 is not reasonable.

Explanation:

Given;

$21,312\div36$

Firstly, let us solve by estimation;

$\begin{gathered} 21,312\approx21,000 \\ 36\approx40 \end{gathered}$

So, we have;

$21,000\text{ }\div\text{ 40 = 525}$

Then we can now divide;

So, by dividing the solution is 592.

$21,312\div36=592$

Therefore, since the estimate is 525 and the actual division gives 592. The difference between the estimate and the actual value is to much. So, the answer 525 is Not Reasonable
