Final answer:
To round 7.25 to the nearest integer, we round down because the decimal part is less than .5, resulting in 7. The correct choice from the provided options is (c) Math.round(7.25).
Step-by-step explanation:
To round the number 7.25 to the nearest integer, we need to look at the decimal part. Since the decimal part (.25) is less than .5, we round down. Therefore, 7.25 rounded to the nearest integer is 7. Looking at the choices provided, the correct method to round a number in most programming languages, specifically JavaScript, would be option (c) Math.round(7.25).
Let's review some general rounding rules: If the first digit to be dropped is 5 or greater, you round up the final digit. For example, 0.028675 rounds "up" to 0.0287 because the dropped digit (7) is greater than 5. Conversely, if the first digit to be dropped is less than 5, then you round down; 18.3384 rounds "down" to 18.3. When rounding a number like 6.8752 where the dropped digit is 5 and a nonzero digit follows it, you would also round up, giving us 6.88.
In some cases such as 92.85, where the dropped digit is 5 and the retained digit is even, some rules suggest rounding down to maintain even distribution, so it rounds "down" to 92.8. However, standard mathematical convention is to always round a 5 up, unless specifically working under guidelines that dictate otherwise.
Therefore, for the given choice, the final answer would be (c) Math.round(7.25).
