MCQ Questions for Class 6 Maths Whole Numbers Quiz 3

Fill the blank space:

$5\times ............... = 31\times ..........$

0%
$5, 31$
0%
$31, 5$
0%
$5, 5$
0%
$31, 31$

Explanation

Whole numbers are commutative under multiplication.

So, for any whole numbers

$a$ and

$b$

$\Rightarrow$

$a\times \underline {b} = \underline {b} \times a$ . [Note that here the first - term becomes the second term and second term becomes the first term]

$\therefore 5\times .............. = \underline {31} \times ............$

$\therefore 5\times 31 = 31\times 5$
Thus, the missing numbers are

$31, 5$ .

The value of

$(147 + 0) + (123 + 0)$ is

0%
$147$
0%
$270$
0%
$123$
0%
$0$

Explanation

$(147 + 0) + (123 + 0) = 147 + 123$

$= 270$ .

$(\therefore 147 + 0 = 147, 123 + 0 = 123)$

Find the missing values:

$52 + (53 + 55) = (..... + ......) + 55$

0%
$55, 52$
0%
$55, 53$
0%
$52, 53$
0%
$52, 52$

Explanation

Addition is associative for whole numbers. i.e.

$a + (b + c) = (a + b) + c$

$\therefore 52 + (53 + 55) = (52 + 53) + 55$

$\therefore$ The missing terms are

$52, 53$ .

Find the missing values:

$25\times (15\times ...... ) = (..... \times 15) \times 10$

0%
$10, 15$
0%
$10, 10$
0%
$15, 25$
0%
$10, 25$

Explanation

Multiplication is of whole numbers is associative in nature that means,

$a\times (b \times c) = (a\times b)\times c$

$\therefore 25 \times (15\times 10) = (25\times 15) \times 10$

Therefore, the missing terms are

$10, 25$ respectively.

For any integer

$'a'$ , the value of

$a + 0 =$

$.....$

0%
$a$
0%
$0$
0%
$1$
0%
$2\ a$

Explanation

The "Additive Identity" of any integer is

$0$ , because adding

$0$ to a number does not change it:

$a + 0 = 0 + a = a$

Thus, for any integer

$'a',$

$a + 0 = a.$

Simplify using associative property:

$(18 + 59) + 1$

0%
$79$
0%
$78$
0%
$76$
0%
$80$

Explanation

$(18 + 59) + 1 = 18 + (59 + 1)$ (associative property)

$= 18 + 60$

$= 78$
(Here, to find the result, we avoided

$18 + 59$ , which could be time consuming).

Simplify using distributive property:

$14\times 6 + 14\times 4 = ...........$

0%
$140$
0%
$38$
0%
$280$
0%
$28$

Explanation

The Distributive Property is easy to remember if you recall that "multiplication distributes over addition".

Formally, they write this property as

$"a(b + c) = ab + ac".$

$14\times 6 + 14\times 4$

$= 14\times (6 + 4)$ (distributive property)

$= 14\times 10$

$= 140$ .

Which of the following number is highlighted on number line?

0%
$2$
0%
$4$
0%
$6$
0%
$8$

Which of the following when added to the additive identity element results

$0$ ?

0%
$1$
0%
$-1$
0%
$0$
0%
$2$

Explanation

The additive identity element is

$0$ .

We know that the sum of

$0$ and any number is the number itself.

Let the number be

$x$ .

$\therefore x + 0 = 0\Rightarrow x = 0$ .

Which of the following shows the distributive property of multiplication over addition?

0%
$(x + 0)\times (y + 0) = x\times y$
0%
$x\times y = y\times x$
0%
$x\times 1 = x$
0%
$x (y + z) = (x\times y) + (x\times z)$

Explanation

$x (y + z) = (x\times y) + (x\times z)$ shows the distributive property of multiplication over addition.

Find the missing values:

$571 + (...... + 394) = (..... + 429) + 394$

0%
$571, 394$
0%
$429, 571$
0%
$571, 429$
0%
$429, 394$

Explanation

Addition is associative for whole numbers

$i.e. a + (b + c) = (a + b) + c$

$\therefore 571 + (429 + 394) = (571 + 429) + 394$

$\therefore$ The missing terms are

$429, 571.$

Fill in the blank:

$17\times 28 + 17\times 22 = 17\times (.... + 22)$

0%
$17$
0%
$22$
0%
$28$
0%
$1$

Explanation

Distributive property states that,

$a\times (b + c) = (a\times b) + (a\times c)$

$\therefore (17\times 28) + (17\times 22) = 17\times (28 + 22)$

Option

$C$ is correct.

Simplify using distributive property:

$[5\times (6)] + [5\times 3] =$

$.....$

0%
$25$
0%
$35$
0%
$45$
0%
$15$

Explanation

$[5\times (6)] + [5\times 3] = 5 [(6) + 3]$ (

$\because$ distributive property)

$= 5[9]$

$=45$ .

Find

$A$ in the following number line?

0%
$10$
0%
$12$
0%
$11$
0%
None of the above

Explanation

On the number line from right to left, the numbers decrease by

$1.$

From the number line, between

$10$ and

$12, 11$ should come. Thus,

$11$ is the value of

$A$ .

State true or false:

Every whole number is a natural number.

0%
True
0%
False

Explanation

Natural numbers

$N =$ Integers from

$1$ to infinity

Whole numbers

$W =$ Integers from

$0$ to infinity

Hence, every natural number is a whole number, but, every whole number is not a natural number.

When we multiply a whole number and the multiplicative identity of whole numbers, then we get _____.

0%
The number itself
0%
The multiplicative identity
0%
0
0%
Negative of that number

Where does the natural numbers ends?

0%
$100$
0%
$1000$
0%
$1000000$
0%
Does not end

The difference between successor and predecessor of any number is

0%
$0$
0%
$1$
0%
$2$
0%
None of these

Explanation

Let the number is

$n$

Then the successor of the number =

$n+1$

and the predecessor of the number =

$n-1$

Difference

$=n+1-(n-1)$

$=n+1-n+1$

$=2$

$0$ is a natural number. Tell true or false

0%
True
0%
False

Explanation

$\text{A natural number is (1, 2, 3, 4, ...) }$

$\text{Zero is not a natural number}$

$\text{option B is correct}$

Add ______ to the previous natural number to get the next natural number.

0%
$0$
0%
$1$
0%
$2$
0%
$3$

Explanation

Since successive natural numbers come have a difference of 1.

Example

$3-2=1$

So , if we add 1 to the previous natural number we get the next natural number.

The set of whole number is denoted by the letter

0%
$N$
0%
$W$
0%
$Z$
0%
$Q$

The whole number 0 has no predecessor.

0%
True
0%
False

Explanation

$\textbf{Step 1: Subtract 1 from 0 to check it has a predecessor or not.}$

$\text{Consider the whole number predecessor 0,}$

$\text{We know that, whole numbers are, }0,1,2,3,4,5,........\infty$

$\text{Now, }$

$0-1=-1$

$\text{Clearly, -1 is not a whole number,}$

$\text{Smallest whole number is }=0$

$\text{So, 0 has no any predecessor;}$

$\textbf{Hence, the given statement is true.}$

The whole number 13 lies between 11 and 12.

0%
True
0%
False

Explanation

Consider the whole number predecessor 0,

We know that, whole numbers are, $0,1,2,3,4,5,........\infty$

Hence, the whole number $=13$ lie between $12$ and $14$

So, $13$ does not lie between $11$ and $12$ ;

$13$ is successor of $12$ and predecessor of $14$ .

Hence, the given statement is False.

State whether the following statement is True or False.
The whole number

$1$ has no predecessor.

0%
True
0%
False

Explanation

False, as

$0$ which is the predecessor of

$1$ is a whole number.

Hence whole number

$1$ has a predecessor.

State whether the following statement is True or False.

$1$ is the smallest whole number.

0%
True
0%
False

Explanation

False,

$0$ is the smallest whole number.

$1$ is the smallest natural number.

$1$ is the identify for the addition of whole numbers.

0%
True
0%
False

Explanation

The given statement is false.

For addition identity is a number which added to the number gives same number.

When

$1$ is added to the whole number

$k$ , it gives next whole number

$k+1$

So, it is not identity for addition of whole numbers.

Zero is identify for the addition of whole numbers.

$\because k+0=0+k=k$ . Where

$k$ is any whole number.

Person

$A$ has

$9$ coins and person

$B$ has

$8$ coins. With the help of number line, both the persons have ____ coins.

0%
$17$
0%
$18$
0%
$18$
0%
$19$

$1$ is the identify for multiplication of whole numbers.

0%
True
0%
False

Explanation

The given statement is true.

For multiplication identity is a number which when multiplied to the number gives same number.

When

$1$ is multiplied to the whole number

$k$ , it gives same whole number

$k$

$\because k\times 1=1\times k=k$ , where

$k$ is any whole number

So, it is identity for multiplication of whole numbers.

Addition of whole numbers is associative.

0%
True
0%
False

Explanation

True, as adding two whole number will always result in a whole number and this addition is associative.

$e.g\ 5+(0+3)=(5+0)+3=8$

$3+(1+2)=(3+1)+2=6$

$0 + 18= 18 + 0$ .

0%
True
0%
False

Explanation

True as addition of whole numbers is commutative.

$0+18=18$

$18+0=18$
