NCERT Solutions for Class 6 Maths Chapter 2 Whole Numbers Ex 2.3
Question 1.
Which of the following will not represent zero :
(a) a + 0
(b) 0 x 0
(c)
(d)
Solution:
(a) 1 + 0 = 1 ≠ 0
(b) 0 x 0 = 0
(c)
(d)
Thus, only (a) does not represent zero.
Question 2.
If the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through examples.
Solution:
We know that the product of any whole number and zero is always zero i. e., a x 0 = 0, where a is any whole number.
Question 3.
If the product of two whole numbers is 1, can we say that one or both of them will be 1? Justify through examples.
Solution:
We know that if a is any whole number, then
a x l = a -1 x a
∴ Clearly a must be = 1
Thus, both the numbers should be 1 i. e., 1 x 1 = 1
Question 4.
Find by using distributive property :
(a) 728 x 101
(b) 5437 x 1001
(c) 824 x 25
(d) 4275 x 125
(e) 504 x 35
Solution:
Question 5.
Study the pattern :
1 x 8 +1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
Write the next two steps. Can you say how the pattern works?
Solution:
Write the next two steps :
123456 x 8 + 6 = 987654
1234567×8 + 7 = 9876543
How the pattern works?
1 x8 + 1= 9
(11 + 1) x 8 + 2 = 12 x 8 + 2 = 98
(111 + 11 + 1) x 8 + 3 = 123 x 8 + 3 = 987 .
(1111 + 111 + 11 + 1) x 8 + 4 =1234 x 8 + 4 =9876
(11111 + 1111 + 111 + 11 + 1) x 8 + 5
= 12345 x 8 + 5=98765
(111111 + 11111 + 1111 + 111 + 11 + 1) x 8+ 6
= 123456 x 8 + 6 = 987654
and (1111111 + 111111 + 11111 +1111 +111 +11 +1) x 8 + 7
= 1234567 x 8 + 7 = 9876543
