Rational numbers are numbers which can be written in the form of a/b. The correct option is A, rational numbers.

What are natural numbers, rational numbers, integers and irrational numbers?

  • Natural numbers are: 1, 2, 3, ....
  • Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )
  • Rational numbers are numbers which can be written in the form of a/b where a and b are integers. Example: 1/2, 3.5 (which is writable as 7/5) etc.
  • Irrational numbers are those real numbers which are not rational numbers.

Know that all natural numbers are integers, and all integers are rational numbers. That means natural numbers are not irrational.

All the counting numbers are a part of whole numbers, but not all the whole numbers are part of counting numbers. Such as zero.

Also, All the whole numbers are a part of integers, but not all the integers are part of whole numbers. Such as negative integers.

Similarly, All the integers are a part of rational numbers, but not all rational numbers are part of integers. Such as decimals.

Thus, it can be concluded that if a number is a member of the set of integers, then it must also be a member of rational numbers.

Hence, the correct option is A, rational numbers.
