 Hi and welcome to the session. Let's discuss the following question. It says state whether the following statements are true or false. Give reasons for your answers. The first statement is every natural number is a whole number. So let us first understand what are whole numbers and what are natural numbers. The whole numbers starts from 0, 1, 2, 3 and so on and the natural numbers are natural numbers are 1, 2, 3, 4 and so on. We can see that the collection of whole numbers contain all the natural numbers. Hence the given statement is true. That is every natural number is a whole number since the collection of whole numbers contains all natural numbers. So this completes the first part. Now the second statement is every integer is a whole number. Now the integers are negative and positive both. That is 0, 1, minus 1, 2, minus 2, 3, minus 3 and so on. And the whole numbers are 0, 1, 2, 3 and so on. Now we can see that integers contain all the negative and positive integers but the whole numbers contain only positive integers. So hence the statement is false. For example, minus 2 is an integer but it is not a whole number. So this completes the second part. Now the third statement is every rational number is a whole number. So let us first understand what is a rational number. Rational numbers are of the form p by q where p and q are integers and q not equal to 0 and the whole numbers are as we discussed 0, 1, 2, 3 and so on. So the given statement is false because for example 1 by 2 is a rational number because it is of the form p by q. It is not a whole number because whole numbers are 0, 1, 2, 3 and so on. So this completes the third part of the question and hence the question. So bye for now. Take care. Hope you enjoyed this session.
