It would be a 30 second seminar. All that you need to translate Binary to Octal is take the binary number and group it into 3 bit groups starting with the LSB and assign the groups their equivlant Octal number.
Binary = Octal
000 = 0
001 = 1
010 = 2
011 = 3
100 = 4
101 = 5
110 = 6
111 = 7
Example:
10100010111010011100001110110012
1 010 001 011 101 001 110 000 111 011 0012 = 121351607318
...so 10100010111010011100001110110012 = 121351607318
If you were going to talk about translating between different numbering systems, you could put together a pretty nice seminar. Allowing for questions would be nice.
Whatever you end up putting together, you have to stress the importance of Zero (0). It is the most important number in the translating from one numbering system to another, because it is the absolute starting point in all numbering systems. It is also the only common symbol in all numbering systems. Without the symbol for nothing, there would be no common reference point for conversion.
1111111010 = octal 1772
Binary number 1110101 equates to octal number 165.
3355
they are both numbers
1111
Octal = 52746757 Binary = 101010111100110111101111
1470 octal = 001 100 111 000 binary
In binary this number is equivalent to 11111000011 while in octal it is 3703
110101001 = 651 octal
Octal 76 = 111110
221122: Binary = 1000100001000100100010 Octal = 10410442 Decimal = 2232610
Don't. 889 is not an octal number.
