1. Convert the positive equivalent to binary.
2. Fill with zeroes, to the left, up to the desired length.
3. Change all 1's to 0's, and all 0's to 1's.
4. Add 1.
Example:
Decimal -12; convert to 2's complement, for a single byte:
1. Convert to binary: 1100
2. Fill with zeroes: 00001100
3. Change 1's and 0's: 11110011

Why does a negative number multiplied by a negative number equals a positive number?
This is NOT a proof, just an explanation. Imagine you are on a number line and you are walking. Multiplying x*y is taking x steps, each of size y. Negative steps are interpreted by requriring you to face the negative end of the line before you start walking and negative step sizes are backward where backward is heel first. This mean to find, -x*-y you stand on zero, face in the negative direction, and then take x backward steps, each of size y.
Why is negative plus negative positive?
A negative plus a negative is a negative number. It is a larger negative number, that is, it is a smaller number - IOW, it is farther to the left on the number line.You probably meant to ask why is a negative number TIMES a negative number a positive number.Think of multiplying m times n as taking m steps, n times. For example, multiplying 3 times 4 means taking three steps - starting at zero and going to the right - four times. When you're done, you will have taken 12 steps to the right.If you multiply 3 times -4, it is like taking 3 steps backwards. Start at zero, take three steps backwards four times and you end up at -12.Multiplying -3 times 4 is like taking backwards steps four times. So take three backwards steps, four times, and you end up at -12.Multiplying -3 times -4 is like taking three backwards steps and going backwards four times. It's like a double reverse.My answer is a short version of a post on mathforum.org (http://mathforum.org/dr.math/faq/faq.negxneg.html). On that page, see the example titled "On the Road" for a good application of why this is true.
How do you convert small to large number?
There are a number of things you could do to the small number: -- Add positive numbers to it. -- Subtract negative numbers from it. -- Multiply it by numbers greater than ' 1 ' . -- Divide it by numbers less than ' 1 '. -- Raise it to positive powers greater than ' 1 '. Repeat any of these steps until the small number grows to the size you want.

How do you convert a number in to a fraction?
I assume you mean a decimal number. Move the point to the right, counting the steps until at last you have no more numbers to the right, or only zeros. Each step is equivalent to multiplying by 10. Suppose there are N steps. The number you now have on the left, divided by 1 followed by N zeros is your fraction. So 1.234 becomes (with 3 steps) 1234/1000
