Question 1

 Write the smallest natural and smallest whole number.

Question 2

Match the column

Closure Property

If a and b are any two whole numbers, then a+b = b+a and a×b = b×a.

Commutative property

If a and b are any two whole numbers, then a+b, axb are also whole numbers.

Associative property

If a, b and c are any two whole numbers, then a(b+c) = a×b + a×c. 

Distributive property

If a, b and c are any two whole numbers, then (a+b)+c = a+(b+c) and (a×b)×c = a×(b×c).

Additive Identity

If a is any whole number, then a + 0 = a = 0 + a.

Multiplicative Identity

If a is any whole number, then a × 0 = 0 = 0 × a.

Multiplication by zero

If a is any whole number, then a × 1 = a = 1 × a

Division by zero

If a is any whole number, then a ÷ 0 is not defined

Distributive Property of Multiplication over Subtraction.

12 x (10 + 85) = 12 x 10 + 12 x 85
 

Associative Property of Addition

71x (11 – 3) = 71 x 11 - 71 x 3
 

Additive Identity

10 x 45 = 45 x 10

Answer

1

The smallest whole number is 0.

2.

Closure Property

If a and b are any two whole numbers, then a+b, axb are also whole numbers.

Commutative property

If a and b are any two whole numbers, then a+b = b+a and a×b = b×a.

Associative property

 If a, b and c are any two whole numbers, then (a+b)+c = a+(b+c) and (a×b)×c = a×(b×c).

Distributive property

If a, b and c are any two whole numbers, then a(b+c) = a×b + a×c.

Additive Identity

If a is any whole number, then a + 0 = a = 0 + a.

Multiplicative Identity

If a is any whole number, then a × 1 = a = 1 × a

Multiplication by zero

If a is any whole number, then a × 0 = 0 = 0 × a.

Division by zero

If a is any whole number, then a ÷ 0 is not defined


3.

191 +13 =13 +191

 Commutative Property of Addition

90 +0 =00

Additive Identity

(78 + 1) + 11 = 78 + (1 +11 )

Associative Property of Addition

(121 x 4) x 80 = 121 x (4 x 80)

Associative Property of Multiplication.

12 x (10 + 85) = 12 x 10 + 12 x 85
 

Distributive Property of Multiplication over Addition.

71x ( 11 – 3 ) = 71 x 11 - 71 x 3
 

Distributive Property of Multiplication over Subtraction.

10 x 45 = 45 x 10

. Commutative Property of Multiplication

 

4)
(a) 18
(b) Addition and Multiplication.
(c) 0.
(d) 1.
(e) 0, 0,Identity element for Addition.

5)   75

6)

 (a) 168 × 102 =168×(100+2)= 16800 + 336=17136
(b) 625 × 279 - 625 ×79 =625×(279-79)= 625×200=125000

8)  Marks obtained by Seema :
Math = 99
English = 69
Science = 91
∴ Total marks obtained by Seema =99 + 69 + 91 = 259
Marks obtained by Rita :
Math = 92
English = 32
Science = 84

So Total marks obtained by John =92 + 33 + 84 = 209

9) 240 chocolates

10) Amount paid for lunch = 45
Amount paid for dinner = 55
Number of days = 7
Money paid by him in 7 days = 7 x (55 +45) = 700
