    How-to: What is (47)8 in decimal?

    The below step-by-step solution shows how to convert (47)8 into decimal equivalent. To find the decimal equivalent of (47)8, multiply 80 with the right most digit, 81 with the left subsequent digit and so on until the left most digit of the given octal number 47. The sum of all individual products is the decimal equivalent of octal 47.
    Solved Example:
    Convert (47)8 into decimal equivalent.
    step 1 Observe the input parameters, values and what to be found.

    Input values:
    Octal Number = 478

    What to be found:
    What is the decimal equivalent of (47)8?

    step 2 Multiply 80 with the right most digit, 81 with the left subsequent digit and so on until the left most digit of the given octal number 47. Therefore, arrange the given decimal number 47 in the expression form as like the below:
    = (4 x 81) + (7 x 80)

    step 3 Resolve the powers of 8 in the above equation:
    = (4 x 8) + (7 x 1)

    step 3 Simplify the above equation further:
    = 32 + 7
    = 39
    (47)2 = (39)10

    Therefore,
    39 is the decimal equivalent of octal number (47)8
