Answer
The answer is 250.
Solution
We start with the calculation:
\[
249 + 1.20
\]
In addition, the result should be reported with the same number of decimal places as the term with the fewest decimal places. The number \(249\) has no decimals (or is understood to have 0 decimal places), while \(1.20\) has 2 decimal places.
First, add the numbers:
\[
249 + 1.20 = 250.20
\]
Now, we round the answer to the nearest whole number (0 decimal places):
\[
250.20 \rightarrow 250
\]
Thus, the final answer is:
\[
\boxed{250}
\]

When you add \( 249 \) and \( 1.20 \), the result is \( 250.20 \). However, when rounding to the correct number of significant figures, you need to consider the least number of decimal places in the original numbers. Since \( 249 \) has no decimal places and \( 1.20 \) has two, your answer should be rounded to no decimal places. Thus, the final answer is \( 250 \). Mathematically: \( 249 + 1.20 = 250.20 \) Rounded correctly: \( 250 \) (with three significant figures).
