The largest family group that includes all of the others is real numbers.
Here's the hierarchy:
- Natural numbers are a subset of whole numbers.
- Whole numbers (natural numbers plus zero) are a subset of integers.
- Integers are a subset of rational numbers.
- Rational numbers include integers and fractions, while irrational numbers are numbers that cannot be expressed as a fraction (like the square root of 2 or π).
- Real numbers encompass both rational and irrational numbers.
So, real numbers is the best answer as it contains all the other sets listed.
