Question 1
1 / -0

The value of $$7 \times (6 \times 5)$$ is equal to

A
$$(7 \times 6) + (7 \times 5)$$

B
$$215$$

C
$$(7 \times 6) \times (7 \times 5)$$

D
$$(7 \times 6) \times 5$$

Solution

$$7 \times (6 \times 5) = 7 \times 30 = 210$$

And $$(7 \times 6) \times 5$$ = $$ 42 \times 5 = 210$$

So, option $$D$$ is correct.
Question 2
1 / -0

Which of the following obey closure property on Integers

A
$$4+3=7$$

B
$$3-4=-1$$

C
$$2-3=-1$$

D
All the above

Solution

$$3$$ and $$4$$ are Integers
$$3+4=7$$
$$7$$ is an integer
$$3$$ and $$4$$ are Integers
$$3-4=-1$$
$$-1$$ is an integer
$$2-3=-1$$
$$-1$$ is an integer
So all the given options obey closure property
So option D is correct.
Question 3
1 / -0

Which of the following is correct?

A
$$5\times 3=3\times 5$$

B
$$12-18=18-12$$

C
$$5-6=6-5$$

D
None otf the above

Solution

$$5\times 3=3\times 5=15$$

$$\left.\begin{matrix}12-18=-6\\ 18-12=6\end{matrix}\right\}6\neq -6$$

$$\left.\begin{matrix}5-6=-1\\ 6-5=1\end{matrix}\right\}-1\neq 1$$

So, option A is correct.
Question 4
1 / -0

Which of the following is correct?

A
$$3\times (4\times 6)=(3\times 4)\times 6$$ is associative property of multiplication

B
$$4\times 6=6\times 4$$ is associative property of multiplication

C
$$12\times 4=4\times 12$$ is associative property of multiplication

D
All of the above

Solution

$$a\times (b\times c)=(a\times b)\times c$$ is accociative property of multiplication.
So, only option A is correct.
Question 5
1 / -0

As per the commutative property, complete the equation for integers for the given operation: $$10\times 5=$$

A
$$500$$

B
$$5\times 10$$

C
$$-50$$

D
None of the above

Solution

$$10 \times 5=5\times10=50$$
This is commutative property of multiplication.
$$5, 10$$ and $$50$$ are integers.
Question 6
1 / -0

$$(-2 \times 4)\times 3=-2 \times (4\times 3)$$ is a

A
closure property

B
commutative property of multiplication

C
associative property of multiplication

D
none of the above

Solution

$$(-2 \times 4)\times 3=-2 \times (4\times 3)$$
It is of the form $$(a \times b)\times c=a \times (b\times c)$$
This is associative property of multiplication.
Question 7
1 / -0

$$-5+(-7)=-7+(-5)$$ is a

A
Closure property

B
Commutative property

C
Associative property

D
None of the the above

Solution

$$-5+(-7)=-7+(-5)$$ is commutative property as,
$$a+b=b+a$$ under commutative property.
Question 8
1 / -0

Check whether closure property is verified for integers for the given operation:$$(-1)\times 23=$$

A
$$-22$$

B
$$23$$

C
Integers are closed under multiplication

D
Integers are not closed under multiplication

Solution

$$-1$$ and $$23$$ are integers.
$$(-1) \times 23=-23$$
$$-23$$ is an integer .
Integers are closed under multiplication.
Question 9
1 / -0

Closure property is not applicable to ......... operation of integers.

A
addition

B
subtraction

C
multiplication

D
division

Solution

When a integer is divided by another integer, the result is not necessarily a integer. Thus, integers are not closed under division.
Question 10
1 / -0

Closure property states that, when any mathematical operation is performed on any two elements of the set, the result is .......... of the set.

A
not a member

B
zero

C
member

D
none of these

Solution

Closure property states that, when any mathematical operation is performed on any two elements of the set, the result is also a member of the set.
