please help to solve this all questions, it would be great if there will be explanation for any steps during solving: Represent the following decimal numbers in both binary sign$/$magnitude and twos

complement using $16$ bits: $+512$; $-29.$

$10\mathrm{.}2$ Represent the following twos complement values in decimal: $1101011$; $0101101.$

$10\mathrm{.}3$ Another representation of binary integers that is sometimes encountered is ones

complement. Positive integers are represented in the same way as sign magnitude. A

negative integer is represented by taking the Boolean complement of each bit of the

corresponding positive number.

a$.$ Provide a definition of ones complement numbers using a weighted sum of bits,

similar to Equations $(10\mathrm{.}1)$ and $(10\mathrm{.}2).$
