Answer :
(i) A whole number is less than all those whole numbers that lie to its right on the number line.
(ii) One more than a given whole is called its successor
(iii) There is at least one whole number between two non – consecutive whole numbers.

Question 1. The height of a slippery pole is 10 m and an insect is trying to climb the pole. The insect climbs 5 m in one minute and then slips down by 4 m. In how much time will insect reach the top?
Answer :
In first 1 min, insect climb 5 metre, then slips down 4 metres.
so it climb 1 metre every 1 min, expect the last minute.
In the last min, it would cover all 5 metres and reach the top.
so keeping 1 min aside for last 5 metres.
Total distance to be
Covered is 10 m, in which we subtract the last 5 m for last climb. so to cover first 5m.
Time required = 5m x 1min = 5 min adding that last 1 min,
it takes 6 min to reach the top of a pole.
Question 2. Which is greater, the sum of first twenty whole numbers or the product of first twenty whole numbers?
Answer :
Sum of the first 20 whole numbers:
0 + 1 + 2 + 3 +…………………… 19 = 190
Product of first 20 whole numbers :
0 x 1 x 2 x 3 x 4 x ………………. x 19 = 0
Hence, sum of the first 20 whole numbers is greater than its product.
Question 3. If a whole number is divisible by 2 and 4, is it divisible by 8 also?
Answer :
May or may not.
Ex.
(i) 12, 20, 28, are the whole number which is divide by both 2 and 4, but is not divisible by 2, 4 and 8.
(ii) 8, 16, 24 are the whole numbers which are divided by 2, 4 and 8.
