Answer:
-22 belongs in integers and rational numbers.
Step-by-step explanation:
-22 can't fit into the natural numbers category because it is a negative number. That also means that it can't go into the whole numbers category. It can fit into the Integers category because it is a number without a fraction. And if it can fit into integers it can fit into the rational numbers as well.
Hope this helped you! ;-D
