  • Question 1
    1 / -0
    The sum of the smallest natural number and the smallest whole number is ............
    Solution
    The smallest natural number is 11 and the smallest whole number is 0. 0.
    1+0=1\therefore 1 + 0 = 1
  • Question 2
    1 / -0
    Commutative property for ........... operation holds true in case of whole numbers.
    Solution
    Commutative property for addition\underline{\text{addition}} holds true in the case of whole numbers.

    For example:
    7+4=117+4=11
    4+7=114+7=11
    7+4=4+7\Rightarrow 7+4=4+7
  • Question 3
    1 / -0
    Which of the following statements is incorrect?
    Solution
    The difference of two whole numbers is not necessarily a whole number. The statement whole numbers are closed under subtraction is an incorrect statement.
  • Question 4
    1 / -0
    Whole numbers are commutative under which of the following operations?
    Solution
    Whole numbers are commutative under addition and multiplication.

    For example
    Take two whole numbers 22 and 5.5.
    Addition =2+5=7=2+5=7 also 5+2=75+2=7, You can add whole nos. in any order which gives same results.  
    Subtraction 25=32-5=-3 also 52=35-2=3 
    Multiplication=2×5=10=2\times 5=10 also 5×2=105\times 2=10 You can multiply whole nos. in any order which gives same results.
    Division=2÷5=0.4=2\div 5=0.4 also 5÷2=2.55\div2=2.5

    Whole numbers are commutative under addition and multiplication.
  • Question 5
    1 / -0
    For any two whole numbers aa and bb which of the following statements is incorrect?
    Solution
    The sum of any two whole numbers and the product of the same are not necessarily equal. 
    Eg. 2+2=4=2×22 + 2 = 4 = 2 \times 2, but 3+3=63 + 3 = 6 and 3×3=93\times 3 = 9 which are not equal.
    Rest all options depicts commutative property which whole numbers satisfy.
  • Question 6
    1 / -0
    For any two whole numbers pp and q,p×q=.........q, p\times q = .........
    Solution
    The value of the product does not change when the order of multiplication gets changed. This is the commutative property of multiplication. 

    Let the two whole numbers be p and q, then p×q=q×p4×9=36=9×4p × q = q × p ⇒ 4 × 9 = 36 = 9 × 4.

    Whole numbers are commutative under multiplication. 
  • Question 7
    1 / -0
    Whole numbers are not closed under __________ operation.
    Solution
    When any whole number is divided by another whole number, the result is not always a whole number. Eg. 2÷3=23=0.6662\div 3 = \dfrac {2}{3} = 0.666. Thus, whole numbers are not closed under division operation.
  • Question 8
    1 / -0
    .......... is associative for whole numbers.
    Solution

  • Question 9
    1 / -0
    Which of the following depicts associative property under addition?
    Solution
    Associative property for addition states that for any three numbers, it does not matter which two are added first and then their sum is added to the third integer the final result will be same
    a+(b+c)=(a+b)+c\therefore a + (b + c) = (a + b) + c
  • Question 10
    1 / -0
    Find the unknown space: .......+142=......+73....... + 142 = ...... +73
    Solution
    Whole numbers are commutative under addition. i.e. a+b=b+aa + b = b + a.
    73+142=142+73\therefore 73 + 142 = 142 + 73.
    \therefore The missing numbers are 73,14273, 142.
