That can refer either to integers, or only to non-negative integers - basically, the counting numbers. (Integers includes negative numbers.) Since "whole numbers" has this ambiguity, it's best to avoid this term. The following is the answer.
No irrational numbers are whole numbers,and all whole numbers are rational.
Whole numbers are integers. Integers are whole numbers.
Whole numbers are a proper subset of decimal numbers. All whole numbers are decimal numbers but not all decimal numbers are whole numbers.
The set of rational numbers includes all whole numbers, so SOME rational numbers will also be whole number. But not all rational numbers are whole numbers. So, as a rule, no, rational numbers are not whole numbers.
Different whole numbers are always whole numbers, but I suspect you meant to ask about the difference between whole numbers. You can subtract two whole numbers and get a negative result. Whole numbers can't be negative.
Whole numbers can be positive or negative numbers. Numbers are whole as long as they have no fractins or decimals with them.
No. Natural numbers are a subset of whole numbers. Negative numbers are whole numbers but not natural.
Yes integers are whole numbers
No, negative numbers are not in the set of whole numbers.
Whole numbers are the same as integers. Whole numbers are a proper subset of rational numbers.
All whole numbers are decimal numbers.
Atomic numbers are always whole numbers!
