## NCERT Solutions for Class 6 Maths Chapter 2 Whole Numbers Ex 2.3

Ex 2.3 Class 6 Maths 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.

Ex 2.3 Class 6 Maths 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.

Ex 2.3 Class 6 Maths 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

Ex 2.3 Class 6 Maths 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:

Ex 2.3 Class 6 Maths 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
