    My number: 175 [Capital “R” <—-Like this one means remainder! ]


    Binary: converted-10101111


    - (Work: 175/2=87 R1, 87/2=43 R1, 43/2=21 R1, 21/2=10 R1, 10/2=5, 5/2=2 R1, 2/2=1, 1/2=0 R1) number from last to first turns out to be —> 10101111


    Octal: converted-257


    - (work: 175/8=21 R7, 21/8=2 R5, 2/8=0 R2) numbers from last to first turns out to be —> 257


    Hexadecimal: converted answer- AF


    - (Work: 175/16=10 R15, 10/16=0 R10) letters from last to first is—> AF

    50/2=25, Re=0

    25/2=12, Re=(0.5)


    Octal:

    400/8=50, Re=0

    50/8=6, Re=(0.25)

    6.25/8=0, Re=(0.78125)

    0.78125/8=0, Re=(0.09765625)

    0.09765625/8=0, Re=(0.01220703125)


    Hexadecimal:

    My Number: 420


    BINARY: 110100100

    420 ÷ 2 = 210 R 0

    210 ÷ 2 = 105 R 0

    105 ÷ 2 = 52 R 1

    52 ÷ 2 = 26 R 0

    26 ÷ 2 = 13 R 0

    13 ÷ 2 = 6 R 1

    6 ÷ 2 = 3 R 0

    3 ÷ 2 = 1 R 1

    1 ÷ 2 = 0 R 1


    OCTAL: 644

    420 ÷ 8 = 52 R 4
