# Class 6 Maths- Exercise 2.1- Question 01 to 05

(1) Write the next three natural numbers after 10999

Next three natural numbers after 10999 are –

10999 + 1 = 11000

11000 + 1 = 11001

11001 + 1 = 11002

Hence, next three natural numbers are 11000, 11001 and 11002

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

Three whole numbers occurring just before 10001 are –

10001 – 1 = 10000

10000 – 1 = 9999

9999 – 1 = 9998

Three whole numbers occurring just before 10001 are 10000, 9999 and 9998

(3) Which is the smallest whole number?

Sol. The numbers from zero to infinity form whole numbers.

Therefore, smallest whole number is 0.

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

For such type of questions, subtract the two numbers and then subtract 1 from the result

Step 1. Subtract both the numbers

53 32 = 21

Step 2. Subtract 1 from the result

21 1 = 20

Therefore, total 20 whole numbers are there between 32 and 53

(5) Write the successor of:

a. 2440701
2440701 + 1 = 2440702
2440702 (Ans)

b. 100199
100199 + 1 = 100200
100200 (Ans)

c. 1099999
