8. Convert/Calculate as per the instruction: 4×1=4
i) (1503)8 = (?)16
Answer:
| Step | Calculation |
|---|---|
| Octal to Binary | 1 = 001, 5 = 101, 0 = 000, 3 = 011 = (1101000011)2 |
| Binary to Hex | 0011 = 3, 0100 = 4, 0011 = 3 = (343)16 |
(1503)8 = (343)16
ii) (101000101)2 = (?)8
Answer:
| Step | Calculation |
|---|---|
| Binary to Octal | 101 = 5, 000 = 0, 101 = 5 |
| = (505)8 |
(101000101)2 = (505)8
iii) (1010 + 1101)2 - (110)2
Answer:
| Step | Calculation |
|---|---|
| Addition | 1010 + 1101 = 10111 |
| Subtraction | 10111 - 110 = 10001 |
(1010 + 1101)2 - (110)2 = (10001)2
iv) (100111)2 / (110)2
Answer:
| Step | Calculation |
|---|---|
| Division | 1010 + 1101 = 10111 |
| 110 | |
| 00111 | |
| 110 | |
| 0011 | |
| 0 | |
| 11 | |
| Result | Q = 110, R = 11 |
