3. CONVERT AS INDICATED

a)     (1375)₈ = (1011111101)₂ = (2FD)₁₆

b)    (A1EF)₁₆ = (1010000111101111)₂ = (A1EF)₁₆

c)     (11101)₂ = (35)₈ = (1D)₁₆

d)    (237.55)₈ = (11101101. 101101)₂ = (ED. 2D)₁₆

e)     (10111.1011)₂ = (27.13)₈ = (17.B)₁₆

f)      (CE13.A2)₁₆ = (1100111000010011. 10100010)₂ = (147023. 242)₈

4. Perform the arithemetic indicated, maintaining your answer in sign-magnitude form. Check your result by converting each problem to decimal and repeating the computation.

a)     (1231)₄ + (1103)₄ = (3000)₄

b)    (135C)₁₆  + (1103)₁₆ = (245F)₁₆

c)     (110101)₂ – (1011)₂ = (101010)₂

d)    (23)₄ X (31)₄ = (10033)₄

e)     (1766)₈ – (23)₈ = (1743)₈

f)      (11101101)₂ / (11101)₂ = (1000)₂
