Any thoughts?

It might help to think about what set 22 does NOT belong to, then you can eliminate any answers that include THAT set.

debbieg · Answer

Your answer choices include:

integers
rational numbers
natural numbers
whole numbers

Which, if any, of those does 22 NOT belong to? which can you justify that it DOES belong to?

All natural numbers are whole numbers.
All whole numbers are integers.
All integers are rational numbers.
