Question 1
1 / -0

Which of the following operations are not associative with respect to whole numbers?

A
addition and subtraction

B
subtraction and division

C
addition and multiplication

D
multiplication and division

Solution

Associative property does not hold good w.r.t. subtraction:
$$A-(B-C) \neq (A-B)-C$$
Associative property does not hold good w.r.t. division as well:
$$A \div (B \div C) \neq (A \div B) \div {C}$$
So, option $$B$$ is correct.
Question 2
1 / -0

The property represented by a $$\displaystyle \times$$ (b + c) = a $$\displaystyle \times$$ b + a $$\displaystyle \times$$ c is

A
commutative property

B
associative property

C
distributive property

D
none of these

Solution

Distributive property can bre written as
a x (b+c) = a x b + a x c
Question 3
1 / -0

Multiplicative identity of whole numbers is ..........

A
1

B
0

C
2

D
Both A and B

Solution

Multiplicative identity is a number with which when multiplied should give the result as the same number.
Question 4
1 / -0

Successor of $$301,999$$ is _____

A
$$300,200$$

B
$$302,000$$

C
$$302,010$$

D
$$301,100$$

Solution

The given number is $$301,999$$
Successor of $$301,999$$$$=301,999 + 1 = 302,000$$
Question 5
1 / -0

Successor of $$100000000$$ is ___________.

A
$$99999999$$

B
$$100000001$$

C
$$10000002$$

D
None of these

Solution

Successor is the number which occurs just after the given number
$$100000000 + 1 = 100000001$$
Question 6
1 / -0

Which of the following expressions is equal to 83 $$\times$$ 5 ?

A
8 $$\times$$ (3 + 5)

B
5 $$\times$$ (8 + 3)

C
5 $$\times$$ (80 + 3)

D
80 $$\times$$ (3 + 5)

Solution

83×5=(80+3)×5
So option C is the correct answer.
Question 7
1 / -0

The natural number which is a multiple of every number is ________.

A
0

B
1

C
There is no such number

D
None of these

Solution

There is no such number which is a multiple of every number!
So option C is the correct option.
Question 8
1 / -0

Which is equal to (4 $$\times$$ 8) + (4 $$\times$$ 60) ?

A
4 $$\times$$ (60 + 8)

B
8 $$\times$$ (60 + 4)

C
12 $$\times$$ (60 + 4)

D
16 $$\times$$ (60 + 8)

Solution

The distributive property of multiplication states that a number is multiplied by the sum of two numbers, when the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.
So(4×8)+(4×60)=4×(8+60)
So, option A is the correct answer.
Question 9
1 / -0

Which of the following represents whole numbers?

A
$$2, 3, 4, 5, .....$$

B
$$...., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ....$$

C
$$1, 2, 3, 4, 5, .....$$

D
$$0, 1, 2, 3, 4, 5, .....$$

Solution

The number $$'0'$$ along with the natural numbers gives us the number set $$\{0, 1, 2, 3, 4, .....\}$$ which is known as set of whole numbers.

Hence, $$0,1,2,3,4....$$ are whole numbers.
Question 10
1 / -0

Which of the following satisfies commutative property?

A
$$12+18=18+12$$

B
$$12-18\neq 18-12$$

C
$$5-6\neq 6-5$$

D
None of the above

Solution

Commutative property means : $$A + B = B + A$$
Since addition satisfies commutative property, so option A is correct.
