Ahh this makes more sense. I have another one, if you could explain me in a similar way - I know the answers to these ones, but i am not sure how .... In base 10, what is the largest 11-bit unsigned binary value? 2047 In base 10, what is the most positive 8-bit two’s complement value? 127 In base 10, what is the most negative 9-bit two’s complement value? -256 This isn't homework, but the solution to it, i just want to know how they are done.

I do know how to convert normal/whole numbers, but i can't do this - Question1) Convert the decimal number 7.52 to binary (8-bits after the binary point, not rounded) ? Question 2) The reverse for the above question - Convert Binary Number 109.0011 to decimal exactly ? Would appreciate if someone can give a explanation to do this without using a calculator, as i want to learn how it is done with pencil and paper. Thank you in Advance.
