Solution:
Task 3: Numbers: From Decimal to Hexadecimal
What is the hexadecimal FF in binary?
1111 1111
Solution:
What is the hexadecimal AB in decimal?
171
Solution:
Convert the hexadecimal FF FF FF to decimal. After you round up the decimal value to the nearest million, how many millions is that?
17
Solution:
Each FF in hex = 255 in decimal.
So:
FFFFFF=(255×2562)+(255×2561)+(255×2560)FF FF FF = (255 × 256²) + (255 × 256¹) + (255 × 256⁰)FFFFFF=(255×2562)+(255×2561)+(255×2560) =(255×65,536)+(255×256)+(255×1)= (255 × 65,536) + (255 × 256) + (255 × 1)=(255×65,536)+(255×256)+(255×1) =16,711,680+65,280+255= 16,711,680 + 65,280 + 255=16,711,680+65,280+255 =16,777,215= 16,777,215=16,777,215
Round to the Nearest Million: 16,777,215 ≈ 17,000,000
That's a wrap!
