Question 2: [10 marks: 2.5 marks each] Assuming an unsigned number system (all numbers are positive), show the maximum number and the smallest unit of increment given 4 integer and 3 fraction positions in the octal number system and their equal decimal values. a) (Max ?)8 = (?)10 b) (Smallest Unit ? )8 = (?)10 Question 4: [10 marks] Show the minimum possible error when converting (16.4)10 to base-4 if only 5 positions are given in total for both integer and fraction parts. Report the error in base-10. Question 5: [10 marks: 2.5 marks each] Show the negative and positive numbers for (86)10 in base-5 using the signed-magnitude and signed- radix-complement number systems, given 10 positions for integer part with no fraction part: a) Positive signed-magnitude b) Negative signed-magnitude c) Positive signed-radix-complement d) Negative signed-radix-complement
