Answer:

The natural numbers along with zero form the collection of whole numbers.

The chapter starts with the introduction on predecessor and successor followed by concept of whole numbers.

If you add 1 to a natural number, we get its successor. If you subtract 1 from a natural number, you get its predecessor.

Every natural number has a successor.

Every natural number except 1 has a predecessor.

Every whole number has a successor.

Every whole number except zero has a predecessor.

All natural numbers are whole numbers, but all whole numbers are not natural numbers.

Question 1:

Write the next three natural numbers after 10999.

ANSWER:

Next three natural numbers after 10999 are

11000, 11001, 11002

Question 2:

Write the three whole numbers occurring just before 10001.

ANSWER:

3 whole numbers just before 10001 are

10000, 9999, 9998

Question 3:

Which is the smallest whole number?

ANSWER:

The smallest whole number is 0.

Question 4:

How many whole numbers are there between 32 and 53?

ANSWER:

Whole numbers between 32 and 53 = 20 (53 − 32 − 1 = 20)

(33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)

Question 5:

Write the successor of:

(a) 2440701 (b) 100199

ANSWER:

(a) 2440701 + 1 = 2440702

(b) 100199 + 1 = 100200

(d) 2345670 + 1 = 2345671

Question 6:

Write the predecessor of:

(a) 94 (b) 10000

ANSWER:

(a) 94 − 1 = 93

(b) 10000 − 1 = 9999

(d) 7654321 − 1 = 7654320

Question 7:

In each of the following pairs of numbers, state which whole number is on the left of the other number on the number line. Also write them with the appropriate sign (>, <) between them.

(a) 530, 503 (b) 370, 307
