Suppose I have the 2&#039;s complement, negative number 1111 1111 1011 0101 (0xFFBB5). How can I represent this as a decimal number in base 10?

If x is an n digit number written in two&#039;s complement, then ∼x+1=−x,where∼ x is the n-digit binary NOT of x. In your case, ∼0xFFBB5+1=0x0044B=1099, so your number is −1099.

Here is the process to convert a negative two's complement number back to decimal:
(1) flip all the bits,
(2) add 1, and
(3) interpret the result as a binary representation of the magnitude and add a negative sign
So, for your example, we have:
$1111111110110101 \Rightarrow 10000000001001010 \Rightarrow 20000000001001011 \Rightarrow 3 - 75$
It looks like you wrote the wrong binary and meant:
$11111111101110110101 \Rightarrow 100000000010001001010 \Rightarrow 200000000010001001011 \Rightarrow 3 - 1099$
Of course, in Hex, you can invert all the bits and add 1 and take a negative magnitude.
