Glance on NCERT Solutions Maths Chapter 2 Exercise 2.1 Class 6 | Vedantu

• NCERT Class 6 Maths Chapter 2 covers topics such as Whole Numbers, The Number Line, Addition on the number line and Multiplication on the number line.

• This chapter focuses on whole numbers, which are the counting numbers starting from 0 and continuing infinitely: 0, 1, 2,3, .... Whole numbers are used for counting objects where fractions or decimals are not involved.

• The number line is a visual representation of whole numbers. Numbers are marked at equal distances on a horizontal line, with 0 in the middle and numbers increasing to the right and decreasing to the left. The number line helps visualize the relative positions of whole numbers and understand addition and subtraction concepts.

• Adding on the number line involves moving a certain number of jumps to the right. Suppose you want to add 3 to 5. Start at 5 on the number line, and move 3 jumps to the right. You land at 8, which is the sum of 5 and 3.

• Multiplication on the number line involves repeated jumps. Multiplying 4 by 2 represents, moving 2 jumps (representing the number being multiplied by) four times to the right. This helps visualize the concept of multiplication with whole numbers.

• The Ex 2.1 Class 6 has 8 Questions and Solutions.

Exercise 2.1

1. Write the next three natural numbers after 10999.

Ans: As we know that to get the next three natural numbers, first of all, we have to add one to 10999 then after adding one to it and after that, we have to add one to the last one.

\$10999+1=11000\$

\$11000+1=11001\$

\$11001+1=11002\$

2. Write the three whole numbers occurring just before 10001.

Ans: As we know that to get the three whole numbers occurring just before 10001, first of all, we have to subtract one from 10001 then after that subtract one from it and finally after that we have to subtract from the last one.

\$10001-1=10000\$

\$10000-1=9999\$

\$9999-1=9998\$

3. Which is the smallest whole number?

Ans: ‘0’ (zero) is the smallest whole number.

4. How many whole numbers are there between 32 and 53?

Ans: 53 – 32 – 1 = 20

There are 20 whole numbers between 32 and 53.

5. Write the successor of:

(a) 2440701

Ans: Successor of 2440701 is 2440701 + 1 = 2440702

(b) 100199

Ans: Successor of 100199 is 100199 + 1 = 100200

(c) 1099999

Ans: Successor of 1099999 is 1099999 + 1 = 1100000

(d) 2345670

Ans: Successor of 2345670 is 2345670 + 1 = 2345671

6. Write the predecessor of:

(a) 94

Ans: The predecessor of 94 is 94 – 1 = 93

(b) 10000

Ans: The predecessor of 10000 is 10000 – 1 = 9999

(c) 208090

Ans: The predecessor of 208090 is 208090 – 1 = 208089

(d) 7654321

Ans: The predecessor of 7654321 is 7654321 – 1 = 7654320

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

Ans: 530 > 503;

So, 503 appear on left side of 530 on number line.

(b) 370, 307

Ans: 370 > 307;

So ,307 appear on left side of 370 on number line.

(c) 98765, 56789

Ans: 98765 > 56789;

So, 56789 appear on the left side of 98765 on a number line.

(d) 9830415, 10023001

Ans: 9830415 < 10023001;

So, 9830415 appear on the left side of 10023001 on the number line.

8. Which of the following statements are true (T) and which are false (F):

(a) Zero is the smallest natural number.

Ans: False, As we know that zero is not a natural number, hence, it can't be the smallest natural number.

(b) 400 is the predecessor of 399.

Ans: False,

The predecessor of any number is the one that comes before the given number on the number line. So, 400 comes after 399 on the number line.

(c) Zero is the smallest whole number.

Ans: True,

Whole numbers start their count from zero, hence, zero is the smallest whole number. The set of whole numbers starts from 0, 1, 2, 3...,

(d) 600 is the successor of 599.

Ans: True

The successor of any number is the one that comes after the given number on the number line. As we know, 600 comes after 599 on the number line.

(e) All natural numbers are whole numbers

Ans: True,

Natural numbers are included in the set of whole numbers. Hence, all natural numbers are whole numbers.

(f) All whole numbers are natural numbers.

Ans: False,

All whole numbers except 0 are natural numbers. Hence, all whole numbers are not natural numbers.

(g) The predecessor of a two digit number is never a single digit number.

Ans: False,

A predecessor comes before the given number on a number line. Hence, it is possible that a single-digit number can come before a two-digit number.

(h) 1 is the smallest whole number.

Ans: False,

Whole numbers start from zero, hence, zero is the smallest whole number.

(i) The natural number 1 has no predecessor.

Ans: True,

Since natural numbers start from 1, it has no predecessor in this list.

(j) The whole number 1 has no predecessor.

Ans: False,

The set of whole numbers starts from 0, 1, 2, 3..., therefore, 1 has a predecessor zero.

(k) The whole number 13 lies between 11 and 12.

Ans: False,

13 ,is a successor of 12. Hence, it does not lie between 11 or 12 i:e 11,12,13.

(l) The whole number 0 has no predecessor.

Ans: True,

The set of whole numbers starts from 0, 1, 2, 3... In this set, 0 has no predecessor.

(m) The successor of a two digit number is always a two digit number.

Ans: False

A successor comes after the given number on a number line. In the case of 99 (a two-digit number), the successor is 100 which is a three-digit number.
