Tell which set or sets the number belongs to: natural numbers, whole numbers, integers, rational
numbers, irrational numbers, and real numbers.
-30
1-irrational, real
2-whole, real
3-integer, rational, real
4-real

Option 3 will be the most appropriate option.

Step-by-step explanation:

The number is given to be -30.

There are some sets 1. natural numbers, 2. whole numbers, 3. integers, 4. rational numbers, 5. irrational numbers, and 6. real numbers given.

Now, we have to find this given number belongs to which given set or sets.

In my opinion, option 3 will be the most appropriate option.  

Since - 30 belong to integers set, rational numbers set and at the same time to real numbers set. (Answer)
