(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
Successor means addition of 1.
2440701 + 1 = 2440702
2440702 (Ans)
b. 100199
Successor means addition of 1.
100199 + 1 = 100200
100200 (Ans)
c. 1099999
Successor means addition of 1.
1099999 + 1 = 1100000
1100000 (Ans)
d. 2345670
Successor means addition of 1.
2345670 + 1 = 2345671
2345671 (Ans)
