Hi! I want to share a method to easily convert a decimal number into binary number and vice versa. I learned this method of converting decimal to binary while I was studying for my C1003 Mathematics for Computing.

The Basic Concept

The basic concept of this method is looking at the fact that we just need to add one zero each time we multiply the decimal equivalent of a binary number by 2 (two).

Let me give an example:

Hi! This is my third post about my International Diploma in Computing assignment. Now I going to post about my C1003 Mathematics for Computing module. I do this module in Term 3 2007 (August – December 2007).

So, lets begin..!!

SECTION A

A1

a) Perform the following base conversions, showing all workings.

i)        3345 Hexadecimal to Denary

3345_{16 =} 13125₁₀

ii)      5714 Octal to Hexadecimal

First step: Octal to Binary

5714₈ = 1011 1100 1100₂

Second step: Binary to Hexadecimal

1011 1100 1100₂ = BCC₁₆

5714₈ = BCC₁₆

iii)    5971 Denary to Binary

5971₁₀ = 1 0111 0101 0011₂

b) Evaluate F9D ₁₆ + 56A ₁₆, showing your working.

F9D₁₆ + 56A ₁₆ = 1507₁₆

A2

For each of the following statement, select one correct answer from those given.
