Yes, you are correct. Answer A, -15, is an example of an integer. An integer is a whole number that can be positive, negative, or zero. In this case, -15 is a negative whole number, so it falls under the category of an integer.
To determine which option is an example of an integer, you need to understand the concept of integers and how they differ from other types of numbers. Integers include all the whole numbers (both positive and negative) as well as zero.
Let's evaluate the other options to see why they are not integers:
- Option B, 3/5, is a fraction, and fractions are not considered integers because they represent parts of a whole number.
- Option C, √7 (sqrt(7)), represents the square root of 7, which is an irrational number. Irrational numbers cannot be expressed as a fraction or a repeating decimal, and therefore, they are not integers.
- Option D, 0.252525, is a repeating decimal. Although it is a rational number (can be expressed as a fraction), it is not an integer because it is not a whole number.
So, your selection of answer A as an example of an integer is indeed correct.
