    Answer:

    125.4

    Step-by-step explanation:

    Given

    Number = 125.3546

    Required

    Round to 1 decimal place

    Up till the first decimal place, the number is:

    Number = 125.3

    The digit after .3 is 5

    The conditions for approximation are:

    • If n > 4, approximate to 1
    • Else: approximate to 0

    In this case: 5 > 4, so we approximate to 1

    Add this “1” to the last digit of 125.3. This becomes 125.4

    Hence: when the number is approximated to 1 decimal place, the digit is 125.4
