QUESTION NO. 1:-

SOLUTION:-

(a)

Convert the above 8-digit binary numbers into decimals. (6 marks)

Solution:

01001000₂ = (0×2⁷) + (1×2⁶) + (0×2⁵) + (0×2⁴) + (1×2 ³) + (0×2²) + (0×2¹) + (0×2⁰)

=0+64+0+0+8+0+0+0

01001000₂ = 72₁₀

 

01101001₂=

 (0×2⁷) + (1×2⁶) + (1×2⁵) + (0×2⁴) + (1×2³) + (0×2²) + (0×2¹) + (1×2⁰)

= 0+64+32+0+8+0+0+1

01101001₂= 105₁₀

 

 00101100₂=

 (0×2⁷) + (0×2⁶) + (1×2⁵) + (0×2⁴) + (1×2³) + (1×2²) + (0×2¹) + (0×2⁰)

=0+0+32+0+8+4+0

 00101100₂= 44₁₀
