Question Question 19
Convert the following binary numbers to octal
(a) 11001
Grouping in bits of 3:
| Binary Number | Equivalent Octal |
|---|---|
| 001 | 1 |
| 011 | 3 |
Therefore, (11001)2 = (31)8
(b) 10101100
Grouping in bits of 3:
| Binary Number | Equivalent Octal |
|---|---|
| 100 | 4 |
| 101 | 5 |
| 010 | 2 |
Therefore, (10101100)2 = (254)8
(c) 111010111
Grouping in bits of 3:
| Binary Number | Equivalent Octal |
|---|---|
| 111 | 7 |
| 010 | 2 |
| 111 | 7 |
Therefore, (111010111)2 = (727)8
