38 + 83 = 83 + 38 is an example of:

0%
Commutative property
0%
Associative property
0%
Closure property
0%
Distributive property

Explanation

Commutative property of addition: Changing the order of addends does not change the sum. For example,

$a+b=b+a$

So according to the above definition correct answer will be Option A

RHS part of the equation

$36(8+3) =$ _______

0%
$38+11$
0%
$(36 \times 8) \times (36 - 3)$
0%
$(36 \times 8) + (36 \times 3)$
0%
$(36 \times 8) + 3$

Explanation

Using distributive formula ,

We can write,

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

So,

$36(8+3)=(36 \times 8) + (36 \times 3)$

Hence,

$Op-C$ is correct.

Predecessor of natural number 1

0%
0
0%
2
0%
10
0%
Does not exist

Explanation

$\textbf{Step -1: Use definition of natural numbers and find range of natural number.}$

$\text{The numbers usually used for counting are called natural numbers.}$

$\text{They range from 1 to infinity.}$

$\text{For example - 1, 2, 3, 4, 5, ...etc.}$

$\text{Hence, 1 being the lowest number in natural numbers, its predecessor does not exist.}$

$\text{Since to find any predecessor of natural number we subtract that number with 1.}$

$\text{here we have to find predecessor of 1 $\Rightarrow$ 1-1 = 0 which is not a natural number.}$

$\textbf{Hence, predecessor of natural number 1 does not exist. (Option D)}$

The whole number which does not have a predecessor is

0%
$100$
0%
$0$
0%
$1$
0%
$9$

Explanation

$\textbf{Step 1: Check which of these numbers has a predecessor.}$

$\text{Whole numbers are 0, 1, 2, 3... and so on.}$

$\text{Predecessor of a number is the number that comes before it.}$

$\text{But since there is no whole number before 0,}$

$\text{the whole number which does not have a predecessor is 0.}$

$\textbf{Hence, Option B is correct.}$

Which of the following statement is true?

0%
Every whole number is a natural number
0%
Every natural number is a whole number
0%
'1' is the least whole number
0%
None of these

Explanation

Natural numbers set is

${1,2,3,......}$
Whole numbers set is

${0,1,2,3,.....}$
Clearly every natural number is a whole number.

Identify the number which when multiplied to the number

$82$ , gives the same number.

0%
$82$
0%
$0$
0%
$\cfrac {1}{82}$
0%
$1$

Explanation

$1$ ' is the only number which when multiplied to any number 82, gives the same number.

So correct answer will be option D

The property satisfied by the division of whole numbers is

0%
Closure property
0%
Commutative property
0%
Associative property
0%
None of these

Explanation

Division of whole numbers does not satisfy any of the properties.

i) Let the divisor be

$0$ .

$\Rightarrow \dfrac{a}{0}$ is not defined for any whole number

$a$

$\Rightarrow \dfrac{a}{0}$ is not a whole number

Therefore, whole numbers are not closed under division.

ii) Consider any 2 whole numbers, say,

$6$ and

$3$ ,

$\dfrac{6}{3} = 2$

$\neq$

$\dfrac{3}{6} = 0.5$

Therefore, division of whole numbers is not commutative

iii)Consider any 3 whole numbers, say,

$2, 4, 8$ .

$\Rightarrow \dfrac{\dfrac{2}{4}}{8} = \dfrac{1}{16}$ and

$\dfrac{2}{\dfrac{4}{8}} = 4$ , i.e

$\Rightarrow \dfrac{\dfrac{2}{4}}{8} \neq \dfrac{2}{\dfrac{4}{8}}$

Therefore, division of whole numbers is not associative.

The property represented by

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

0%
Commutative property
0%
Associative property
0%
Distributive property
0%
None of these

The value of

$555 \times 193 + 555 \times 93$ is

0%
$555,931$
0%
$1,210,321$
0%
$53,912$
0%
$158730$

Explanation

Given that , we have to find the value of given expression

$555 \times 193 + 555 \times 93$

Taking

$555$ common

$\Rightarrow 555 \times (193 + 93)$

$\Rightarrow 555 \times (286) = 158730$

So option

$D$ is correct

The property represented by

$a + b = b + a$ is

0%
Associative property
0%
Commutative property
0%
Closure property
0%
Additive identity

Explanation

Commutative property of addition: Changing the order of addends does not change the sum. For example,

$a+b=b+a$

So correct answer will be option B

0%
$4980$
0%
$49,800$
0%
$498,000$
0%
None

Explanation

$498 \times 73 + 498 \times 27$

$= 498 \times (73 + 27)$

$= 498 \times 100 = 49800$

Multiplicative identity of whole number is given by

The counting numbers

$1,2,3,4,....$ are called

0%
whole number
0%
natural numbers
0%
integers
0%
None of these

Explanation

Natural numbers are the set of whole numbers

$($ except

$0).$

The numbers

$1,2,3,4,5.......$ are called natural numbers.

Which of the following options defines associative property for whole numbers?

0%
$0+(8+5) = (0+8)+5$
0%
$0 \times (8+5) = (0+8) \times 5$
0%
$0-(8 \div 5) = (0-8) \div 5$
0%
$0 \div (8 \div 5) = (0 \div 8) \div 5$

Explanation

LHS

$=0+(8+5)$ =

$0+13 = 13$
RHS

$= (0+8)+5$ =

$8+5 = 13$
LHS

$=$ RHS
Therefore, option A is correct.

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

0%
addition and subtraction
0%
subtraction and division
0%
addition and multiplication
0%
multiplication and division

Explanation

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.

The property represented by a

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

$\displaystyle \times$ b + a

$\displaystyle \times$ c is

0%
commutative property
0%
