Answer :
Certainly! Let's explore which sets the number 84 belongs to:
1. Natural Numbers: These are the numbers used for counting and normally start from 1 (1, 2, 3, ...). Since 84 is a positive whole number, it is indeed a natural number.
2. Whole Numbers: Whole numbers include all natural numbers and the number 0 (0, 1, 2, 3, ...). Since 84 is a natural number, it is also a whole number.
3. Integers: Integers are all whole numbers and their negatives (-3, -2, -1, 0, 1, 2, 3, ...). Since 84 is a whole number, it is an integer.
4. Rational Numbers: A rational number is any number that can be expressed as the fraction of two integers, where the denominator is not zero. Since 84 can be written as 84/1, it is a rational number.
5. Real Numbers: Real numbers include all the numbers that can be found on the number line, including both rational and irrational numbers. Since 84 is a rational, and therefore a real number, it belongs to this set.
6. Irrational Numbers: These are numbers that cannot be expressed as a simple fraction (like √2 or π). Since 84 can be expressed as a fraction (84/1), it is not an irrational number.
In summary, the number 84 belongs to the sets of natural numbers, whole numbers, integers, rational numbers, and real numbers. It is not an irrational number.
