Question

45, -72, and 0 all are examples of:

Positive integers
Negative integers
Irrational numbers
Integers

Answer 1

Integers

Explanation:

They are not all positive integers because -72 is negative.

They are not all negative because 45 is positive. The + sign is implied.

They are all whole numbers and not irrational.

Thus, they are integers, which by looking at the data, we see is true.
