Final answer:
0 falls into several number groups including integers, whole numbers, rational numbers, and real numbers.
Step-by-step explanation:
0 falls into several number groups:
- Integers: Integers are whole numbers, both positive and negative, including zero. So, 0 is an integer.
- Whole Numbers: Whole numbers are non-negative integers, including zero. Thus, 0 falls into this category as well.
- Natural Numbers: Natural numbers are positive integers, excluding zero. Therefore, 0 does not fall into this category.
- Rational Numbers: Rational numbers can be expressed as a fraction, where the numerator and denominator are both integers. Zero can be written as 0/1, so it can be expressed as a fraction, making it a rational number.
- Real Numbers: Real numbers include all rational and irrational numbers. Since 0 is a rational number, it is included in this category.
- Real Numbers: Irrational numbers cannot be written as a fraction and have non-repeating, non-terminating decimal representations. Since 0 can be written as 0/1, it is not considered an irrational number.
