## NCERT Solutions for Class 6 Maths, chapter 2, Whole Numbers, Exercise 2.1

**Q.1. Write the next three natural numbers after 10999.**

**Ans: **The next three natural numbers after 10999 are

10,999 +1 = 11,000

11,000 +1 = 11,001

11,001 +1 = 11,002

Hence, the next three natural number after 10,999 are 11,000, 11,001 and 11,002.

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

**Ans: **The three whole numbers occurring just before 10001 are

10,001 -1 = 10,000

10,000 -1 = 9,999

** **9,999 – 1 = 9,998

Hence, the three whole numbers occurring just before 10001 are 10,000, 9,999 and 9,998.

**Q.3. Which is the smallest whole number?**

**Ans: **The smallest whole number is 0 (Zero).

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

**Ans: **The whole numbers between 32 and 53 = 53 – 32 – 1 = 20

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

Hence, there are 20 whole numbers between 32 and 53

**Q.5. Write the successor of : ****(a) 2440701 (b) 100199 (c) 1099999 (d) 2345670**

**Ans: **The successors of:

(a) 2440701 + 1 = 2440702

(b) 100199 + 1 = 100200

(c) 1099999 + 1 = 1100000

(d) 2345670 + 1 = 2345671

**Q.6. Write the predecessor of : ****(a) 94 (b) 10000 (c) 208090 (d) 7654321**

**Ans: **The predecessors of:

(a) 94 – 1 = 93

(b) 10000 – 1 = 9999

(c) 208090 – 1 = 208089

(d) 7654321 – 1 = 7654320

**Q.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 (c) 98765, 56789 (d) 9830415, 10023001**

**Ans: ****(a) Since, 530 > 503**

Hence, 503 appear on the left side of 530 on the number line.

**(b) Since, 370 > 307**

Hence, 307 appear on the left side of 370 on the number line.

**(c) Since, 98765 > 56789**

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

**(d) Since, 9830415 < 10023001**

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

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

**(a) Zero is the smallest natural number. **

**(b) 400 is the predecessor of 399.**

**(c) Zero is the smallest whole number. **

**(d) 600 is the successor of 599.**

**(e) All natural numbers are whole numbers.**

**(f ) All whole numbers are natural numbers.**

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

**(h) 1 is the smallest whole number.**

**(i) The natural number 1 has no predecessor.**

**(j) The whole number 1 has no predecessor.**

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

**(l) The whole number 0 has no predecessor.**

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

**Ans:**
