By definition we have to: ** Rational number** is any number that can be represented as the quotient of two whole numbers or, more precisely, an integer and a positive natural. We then have the following number: 24/6 Rewriting we have: 24/6 = 4 We observe then that we also have a natural number because it belongs to the set: ℕ = {1, 2, 3, 4, ...} Whole number because it belongs to the set: Z = {..., - 3, -2, -1,0, + 1, + 2, + 3, ...} Real number because this set covers all the numbers: Rational, irrational, whole and natural. **Answer: ** The error of Damarcus is not to rewrite the number. Therefore, he did not realize that the number does belong to other sets of numbers

Damarcus is mistaken in believing that 6 24 ​ only belongs to the set of rational numbers. Upon simplification, 6 24 ​ equals 4 , which is also a member of the natural, whole, and integer numbers. Thus, it falls under multiple categories of numbers.
