Question

Classify the number as natural, whole, integer, rational, and/or irrational.

Answer 1

The set of natural numbers is {1, 2, 3, 4, ...} basically positive whole numbers

The set of whole numbers is {0, 1, 2, 3, ...} which is the set of natural numbers with 0 included

The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} consisting of positive and negative whole numbers, plus zero as well

The set of rational numbers is the set of all fractions of the form a/b where b is not equal to zero. Any whole number, natural number, and integer is also a rational number.

If the number cannot be expressed as a rational number, then it is said to be irrational

------------------------------------------------------------------------

With all that in mind, the answers are "integer" and "rational" as you wrote in the comment section above. The value -25 is in the set {..., -3, -2, -1, 0, 1, 2, 3, ...} which is the set of integers. So we can say that -25 is an integer.

-25 is not a whole number based on the definition I wrote above. The set of whole numbers I wrote above does not include any negative values. This is why -25 is not a natural number either.

We can say that -25 is rational since -25 = -25/1 which is a fraction of integers. Since -25 is rational, it cannot be irrational. 

Answer 2

Integer and rational :)


edit. just saw that you put that sorry haha but ya ur right.
