Final answer:
The number 14 belongs to the subsets of natural, whole, integer, and rational numbers, since it is a positive integer that can also be expressed as a fraction with an integer numerator and a non-zero integer denominator.
Step-by-step explanation:
The number 14 belongs to several subsets of real numbers. Specifically, the subsets it belongs to are natural numbers, whole numbers, integers, and rational numbers. This is because:
- Natural numbers are the set of positive numbers starting from 1, which includes 14.
- Whole numbers are the set of natural numbers together with 0, so 14 is also a whole number.
- Integers are all whole numbers including the negatives, so 14 is also an integer.
- Rational numbers are numbers that can be expressed as a fraction with an integer numerator and a non-zero integer denominator. Since 14 can be expressed as 14/1, it is a rational number.
Therefore, the correct answer is A. natural, whole, integer, rational.
