Amar Kumar answered |
Integers include 0 and the opposites (negatives) of natural numbers, and whole numbers include 0 while natural numbers do not. The result is that natural numbers are a subset of whole numbers which are in turn a subset of integers which you correctly categorized as a subset of rational numbers.

Varun Kapoor answered |
Solution:
The correct option is C 0.0
An element, which when added to a given element, leaves the given element unchanged, is called its additive identity.
Zero is the additive identity for all the real numbers.
For example, 24+0=24.

Komal patil answered |
Closure Property: The closure property means that a set is closed for some mathematical operation. For example, the set of even natural numbers, [2, 4, 6, 8, . . .], is closed with respect to addition because the sum of any two of them is another even natural number, which is also a member of the set.

Shubham Gupta answered |
Explanation:
The statement "Every natural number is a whole number" is true. Let's understand why by exploring the definitions of natural numbers and whole numbers.
Natural Numbers:
Natural numbers are the counting numbers that start from 1 and go on infinitely. They are also known as positive integers. In other words, natural numbers are the numbers we use for counting or ordering objects. The set of natural numbers is denoted by N.
Whole Numbers:
Whole numbers are the numbers that include zero along with the natural numbers. They are obtained by adding zero to the set of natural numbers. The set of whole numbers is denoted by W.
Understanding the Statements:
a) Every whole number is a natural number.
This statement is false. While every natural number is a whole number, not every whole number is a natural number. Whole numbers include zero, which is not a natural number.
b) Every natural number is a whole number.
This statement is true. Since whole numbers include zero along with the natural numbers, every natural number is also a whole number.
c) 1 is the least whole number.
This statement is false. Zero is the least whole number because it is the starting point of the set of whole numbers.
d) 0 is the greatest whole number.
This statement is false. Whole numbers go on infinitely, so there is no greatest whole number. Zero is the starting point of whole numbers, but there is no end or greatest whole number.
Conclusion:
Based on the definitions of natural numbers and whole numbers, the true statement is that every natural number is a whole number (option B).

Anisha Iyer answered |
Solution:
To solve this problem, we have to multiply each digit by its corresponding place value and then add the products together.
The given expression can be written as:
3 x 10000 + 7 x 1000 + 9 x 100 + 0 x 10 + 4
Multiplying each digit by its place value, we get:
30,000 + 7,000 + 900 + 0 + 4
Adding these products together, we get:
37,904
Therefore, the correct answer is option 'C'.

Dr Manju Sen answered |
Concept:
Counting the whole numbers within the given range.
Solution:
⇒ The sequence of whole numbers between 0 and 10 is: 1, 2, 3, 4, 5, 6, 7, 8, 9
⇒ We simply need to count these numbers.
⇒ There is 1 one. ⇒ There is 1 two. ⇒ There is 1 three. ⇒ There is 1 four. ⇒ There is 1 five. ⇒ There is 1 six. ⇒ There is 1 seven. ⇒ There is 1 eight. ⇒ There is 1 nine.
by adding all the counts, we get 9 whole numbers between 0 and 10.
Hence, the correct answer is "9".
