In whole numbers, closure property is not satisfied with respect to operations _________.

A
(+,-)

B
(+, x)

C
(-, x)

D
(-, -)

Solution

In whole numbers, closure property is not satisfied with respect to operations (-, -)
Question 2
1 / -0

Every natural number is the successor of ________ number.

A
Whole

B
Natural

C
Integer

D
None of these
Question 3
1 / -0

Which of the following statements is NOT true?

A
0 + 0 = 0

B
0 − 0 = 0

C
0 × 0 = 0

D
0 ÷ 0 = 0
Question 4
1 / -0

If a and b are two whole numbers, then commutative law is applicable on subtraction if and only if ________.

A
a = b

B
a ≠ b

C
a > b

D
a < b

Solution

If a = b, then a ? b = a ? a = 0 and b ? a = a ? a = 0 i.e., a - b = b - a
Question 5
1 / -0

(25×22) × 25 = 25 × (22×25) is an example of______ property.

A
Commutative

B
Associative

C
Closure

D
Distributive

Solution

(25×22) × 25 = 25 × (22×25) is an example of Associative property.
Question 6
1 / -0

Which of the following operations satisfies the associative law for whole numbers?

(7+8) + 9=7 + (8+9)

B
(7×8) × 9=7 × (8×9)

C
7 + 8 × 9 = (7+8) × (7+9)

D
7 × (8+9) = (7×8) + (7×9)

Solution

7+8×9=7+72=79, (7+8)×(7+9)=15×16=240 And 79≠240
