Witch number set does 5 belong to
5 belongs to the set of natural numbers (N), integers (Z), rational numbers (Q), and real numbers (R).
The number 5 belongs to the set of natural numbers. Natural numbers are the set of positive whole numbers starting from 1 and extending indefinitely (1, 2, 3, 4, 5, ...).
To determine which number set 5 belongs to, we need to know the context or the specific set in question. There are several different number sets commonly used in mathematics. Here are a few examples:
1. Natural Numbers: The set of natural numbers, denoted by N, includes all positive whole numbers starting from 1 and going infinitely. So in this set, 5 belongs.
N = {1, 2, 3, 4, 5, ...}
2. Integers: The set of integers, denoted by Z, includes all positive and negative whole numbers and zero. So in this set, 5 belongs.
Z = {..., -3, -2, -1, 0, 1, 2, 3, ...}
3. Rational Numbers: The set of rational numbers, denoted by Q, includes all numbers that can be expressed as a ratio of two integers, with the denominator not equal to zero. Every whole number is also a rational number, so 5 belongs to this set as well.
Q = {..., -2, -1, 0, 1, 2, 3, ...}
There are other number sets such as real numbers (R) and complex numbers (C), but none of them exclude 5.
So, it depends on the context, but in most commonly used number sets, 5 would be included.
