1. is not an integer. An integer is a whole number that can be positive, negative, or zero. is a fraction.2. 2 is a real number. Real numbers include all rational and irrational numbers. 2 is a rational number, and therefore, it is also a real number.3. is not a rational number. A rational number can be expressed as a fraction of two integers. is an irrational number because it cannot be expressed as a fraction of two integers.4. is a real number. is an irrational number, which means it cannot be expressed as a fraction of two integers. However, it is still a real number.5. is an integer. Integers include all positive and negative whole numbers, including zero. is a negative whole number, so it is an integer.6. is a rational number. is equal to 7, which can be expressed as a fraction of two integers (7/1). Therefore, it is a rational number.7. 0 is not a natural number. Natural numbers are typically defined as positive whole numbers starting from 1. However, some definitions of natural numbers include 0. In this case, 0 is not considered a natural number.
