(a) 111010
Grouping in bits of 3:
Binary Number | Equivalent Octal |
---|---|
010 | 2 |
111 | 7 |
Therefore, (111010)2 = (72)8
(b) 110110101
Grouping in bits of 3:
Binary Number | Equivalent Octal |
---|---|
101 | 5 |
110 | 6 |
110 | 6 |
Therefore, (110110101)2 = (665)8
(c) 1101100001
Grouping in bits of 3:
Binary Number | Equivalent Octal |
---|---|
001 | 1 |
100 | 4 |
101 | 5 |
001 | 1 |
Therefore, (1101100001)2 = (1541)8
