Final answer:
The number 71 belongs to several different sets in mathematics, including Natural numbers, Whole numbers, Rational numbers, Integers, and Real numbers. This is because it can be expressed as a positive whole number, a ratio of two integers, and it is a real number.
Explanation:
The number 71 belongs to several different sets in the field of mathematics. The sets that the number 71 belongs to are: Natural numbers, Whole numbers, Rational numbers, Integers, and Real numbers. Firstly, Natural numbers are all positive numbers starting from 1 (1, 2, 3, 4, etc.), hence 71 belongs here. Whole numbers are similar to natural numbers, but they also include 0, and as 71 is positive, it also belongs to this set.
Rational numbers are numbers that can be expressed as a fraction of two integers, and as 71 can be written as 71/1, it fits into this set too. Integers are all whole numbers, both positive and negative, including 0, so 71 is part of this set. Lastly, Real numbers include all rational and irrational numbers, so as 71 is a rational number, it is also a real number.
