6th class maths textbook solutions  Problem 1

1. Which of the following will not represent zero:

a. 1 + 0

b. 0 × 0

c. 0/2

d. 10 × 0/2

Solution: a. (1 + 0 = 1) Problem 2

2. If the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through example.

Solution: Yes. If we multiply any number with zero, the product will be zero. Example: 1 × 0 = 0, 3 × 0 = 0 If both numbers are zero, the product also be zero. Example: 0 × 0 = 0 Problem 3

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: If we multiply any number with 1 the product cannot be 1. Example: 3 × 1 = 3, 5 × 1 = 5 If both numbers are 1, then the product is 1. Example: 1 × 1 = 1 Problem 4

4. Find using distributive property:

a. 728 × 101

b. 5437 × 1001

c. 824 × 25

d. 4275 × 125

Solutions: a. 728 × 101 = 728 × (100 + 1) = 728 × 100 + 728 × 1 = 72,800 + 728 = 73,528 b. 5437 × 1001 = 5437 × (1000 + 1) = 5437 × 1000 + 5437 × 1 = 54,37,000 + 5437 = 54,42,437 c. 824 × 25 = 824 × 25 × 4/4 = 824 × 100 /4 = 82400/4 = 20,600 d. 4275 × 125 = 4275 × 125 × 8/8 = 4275 × 1000/8 = 42,75,000/8 = 5,34,375 e. 504 × 35 = 504 × 35 × 2/2 = 504 × 70 / 2 = 35280 /2 = 17,640 Problem 5

5. Study the pattern:

1 × 8 + 1 = 9

12 × 8 +2 = 98

123 × 8 +3 = 987

1234 x 8 + 4 = 9876

12345 × 8 +5 = 98765

Write the two new steps. Can you say the pattern works?

(Hint: 12345 = 11111 + 1111 + 111 + 11 + 1).

Solution: 1 × 8 + 1 = 9 12 × 8 +2 = 98 123 × 8 +3 = 987 1234 x 8 + 4 = 9876 12345 × 8 +5 = 98765 123456 × 8 +6 = 987654 1234567 × 8 + 7 = 9876543 NOTE : Observe the solutions and try them in your own method. Inter maths solutions NCERT class 7 maths solutions SSC Maths class 10 solutions
