The property satisfied by addition or multiplication of whole numbers is ____________.

A
commutative property

B
associative property

C
closure property

D
None of these

Solution

The associative property states that you can add or multiply regardless of how the numbers are grouped.
(a + b) + c = a + (b + c)
(a × b) × c = a × (b × c)
Question 3
1 / -0

(3 + 4) × 1 = (3 × 1) + (4 × 1) is an example of ____________.

A
associative property

B
distributive property

C
closure property

D
commutative property

Solution

It is an example of distributive property. The distributive property tells us how to solve expressions of the form a(b + c).
Question 4
1 / -0

Which symbol will replace the question mark (?) below?

Place value of 5 in 4,154,129 ? Place value of 5 in 3,548,127

A
=

B
>

C
<

D
None of these

Solution

Place value of 5 in 4,154,129 = 50,000
Place value of 5 in 3,548,127 = 5,00,000
Place value of 5 in 4,154,129 < Place value of 5 in 3,548,127

A
100590

B
100589

C
100587

D
100550

Solution

The successor of 100588 = 100588 + 1 = 100589
Question 7
1 / -0

If p, q and r are three whole numbers, then the associative law is applicable on addition, if and only if

A
p - r = 0

B
p + q = 0

C
p = r

D
p ≠ r

Solution

Associative law in addition,
(p + q) + r = p + (q + r)
Hence, it will be applicable if p ≠ r.
Question 8
1 / -0

How many whole numbers are there between 32 and 94?

A
45

B
61

C
60

D
55

Solution

Number of whole numbers between 32 and 94 is 94 - 32 - 1 = 61
Question 9
1 / -0

Which of the following sets of numbers will make the given number sentence true?

________ + __________ - _________ = 25

A
5, 15, 20

B
10, 20, 5

C
5, 10, 20

D
15, 10, 10

Solution

5 + 15 - 20 = 0

10 + 20 - 5 = 25

5 + 10 - 20 = -5

15 + 10 - 10 = 15
Question 10
1 / -0

Which of the following is not true?

A
5 + 6 × 7 = (5 + 6) × (5 + 7)

B
(5 × 6) × 7 = 5 × (6 × 7)

C
(5 + 6) + 7 = 5 + (6 + 7)

D
5 × (6 + 7) = (5 × 6) + (5 × 7)

Solution

(i) 5 + 6 × 7 = (5 + 6) × (5 + 7)
5 + 42 = 11 × 12
47 ≠ 132

(ii) (5 × 6) × 7 = 5 × (6 × 7)
30 × 7 = 5 × 42
210 = 210

(iii) (5 + 6) + 7 = 5 + (6 + 7)
11 + 7 = 5 + 13
18 = 18

(iv) 5 × (6 + 7) = (5 × 6) + (5 × 7)
5 × 13 = 30 + 35
65 = 65
