    The options 1,2 and 5 are the correct answer.
    The given equation is 1.23/[tex]10^1[/tex]=0.123.

    What is the division?

    The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
    Now,
    1) 1.23/[tex]10^1[/tex]=0.123
    Here LHS=RHS
    2) 123/100=1.23
    Here LHS=RHS
    3) 12.3/[tex]10^0[/tex]=1.23
    ⇒ 12.3/1=12.3
    So, LHS≠RHS
    4) 0.123/10=1.23
    ⇒ 0.123/10 = 0.0123
    So, LHS≠RHS
    5) 1230/10³=1.23
    ⇒ 1230/1000
    = 1.23
    Here LHS=RHS
    Therefore, the options 1,2 and 5 are the correct answer.
