    How-to: What is 11101 binary in decimal?

    The below step-by-step solution shows how to convert 11101 binary to its equivalent decimal number. The sum of increasing power of 2 (from 0 to number of bits minus 1) for each bit of given binary number 11101, that is 20 multiplied with least significant digit (LSD) to 2(no. of bits - 1) multiplied with the most significant digit (MSD) of the given base-2 number provides the equivalent decimal number. What is the decimal equivalent of the binary number 11101?
    step 1 Observe the input parameters, values and what to be found.

    Input values:
    Binary Number = 111012

    What to be found:
    What is 11101 binary in decimal?

    step 2 Arrange the given binary number 11101 as like the below:
    = 1 x 24 + 1 x 23 + 1 x 22 + 0 x 21 + 1 x 20,

    step 3 Resolve the powers of 2 in the above equation:
    = 16 + 8 + 4 + 0 + 1,

    step 3 Simplify the above equation further:
    = 16 + 8 + 4 + 0 + 1,
    = 16 + 8 + 4 + 0 + 1,
    = 29
    (11101)2 = (29)10

    Therefore,
    29 is the decimal equivalent of binary number 11101
