To check the reasonability of an answer, you can use the whole number expression 248 divided by 4. Let's say your answer to Exercise 2 involves a division or is related to dividing a quantity. In that case, you can use the fact that 248 divided by 4 equals 62.

Verify Quotient: Check if your answer is close to the quotient of 248 divided by 4, which is 62. If your answer is significantly different, it might be worth double-checking your calculations.

Estimation: If your answer is an estimate or an approximation, see if it aligns with the 248 divided by 4. Estimating with whole numbers can help quickly assess reasonability.

Sanity Check: If your answer doesn't make sense in the context of the problem, reconsider your calculations. For example, if you're calculating the average or distributing a quantity among four parts, ensure that the result aligns with the idea of dividing 248 into four equal parts.

Using 248 divided by 4 as a reference point provides a quick and easy way to make sure your answer is in the right ballpark and helps catch any potential errors in your calculations.
