    Solution

    The smallest two digit number is 10, which has (10 - 1) = 9 as single digit predecessor

     

  • Question 4
    1 / -0

    The most suitable rearrangement to solve 5 × 263 × 20 is

    Solution

    The most suitable way is as follows.

    5 × 263 × 20

    = 5 × 20 × 263        [Using commutative property]

  • Question 6
    1 / -0

    Which property of whole numbers is shown in 255 × 1 = 255?

    Solution

    As per Multiplicative Identity of whole numbers, a × 1 = a = 1 × a

     

  • Question 7
    1 / -0

    Name the property used to write 218 × 102 = 218 × 100 + 218 × 2

    Solution

    218 × 102 = 218 x (100 + 2)

    As per Distributive property of multiplication over addition, a ×(b + c) = a × b + a × c

    So, 218 x (100 + 2) = 218 × 100 + 218 × 2
