Question 2
Perform the following conversations in the stated number bases:
(a) AB116 to octal system:
(b) 1110111.1012 to denary system:
(c) 5078 to binary system.
Observation
The question tested candidates’ knowledge on conversion of numbers from one base to another.
The expected answer is:
- AB1Hex to octal
A B 1
1010 1011 0001 ___Step 1
=1010101100012
=101 010 110 001 _______Step 2
=5 2 6 1
=5261Octal ___________Step 3
OR SECOND METHOD
= 273710
