## EXERCISE 2.1

**(1) Write the next three natural numbers after 10999.**

Ans: 11,000; 11,001; 11,002

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

Ans: 10,000; 9,999; 9,998

**(3) Which is the smallest whole number?**

Ans: 0

**(4) How many whole numbers are there between 32 and 53?**

Ans: 20

**(5) Write the successor of:**

(a) 2440701 = (24,40,701 + 1) = 24,40,702

(b) 100199 = (1,00,199 + 1) = 1,00,200

(c) 1099999 = (10,99,999 + 1) = 11,00,000

(d) 2345670 = (23,45,670 + 1) = 23, 45,671

**(6) Write the predecessor of:**

(a) 94 = (94 – 1) = 93

(b) 10000 = (10,000 – 1) = 9,999

(c) 208090 = (2,08,090 – 1) = 2,08,089

(d) 7654321 = (76,54,321 – 1) = 76,54,320

**(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 = 503 is on the left of 530; 503 < 530

(b) 370, 307 = 307 is on the left of 370; 307 < 370

(c) 98765, 56789 = 56,789 is on the left of 98,765; 56,789 < 98,765

(d) 9830415, 10023001 = 98,30,415 is on left of the 1,00,23,001;

Therefore; 98,30,415 < 1,00,23,001

(a) Zero is the smallest natural number. = F

(b) 400 is the predecessor of 399. = F

(c) Zero is the smallest whole number. = T

(d) 600 is the successor of 599. = T

(e) All natural numbers are whole numbers. = T

(f) All whole numbers are natural numbers. = F

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

(h) 1 is the smallest whole number. = F

(i) The natural number 1 has no predecessor. = T

(j) The whole number 1 has no predecessor. = F

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

(l) The whole number 0 has no predecessor. = T

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