Question

Which of the following groups are subsets of rational numbers

Answer 1

Answer: Option I,II,III, IV, are the subsets of rational numbers.

Step-by-step explanation:

Since we know that

Rational number is the set of numbers which is belong to real integers, integers, whole numbers and natural numbers.

But irrational numbers are those numbers are not rational numbers and which cannot be written in the form of $\frac{p}{q}$

So, Option I,II,III, IV, are the subsets of rational numbers.

Answer 2

None of the above. There are real numbers that aren't rational (these are the irrational numbers). Some rational numbers are integers, but not all. The same goes for natural numbers. And irrational numbers are numbers that are not rational.
