$1\mathrm{.}1$ Convert to hexadecimal and then to binary: $($c$)$

$356\mathrm{.}8910$

$1\mathrm{.}12($a$)$ Convert to base $3$: $375\mathrm{.}548($do all of the

arithmetic in decimal$).$

$1\mathrm{.}16$ Convert the following decimal numbers to octal

and then to binary: $($d$)109\mathrm{.}30$

$1\mathrm{.}17$ Add, subtract and multiply in binary: $($c$)110010$

and $11101$

$1\mathrm{.}20$ Divide in binary: $($b$)110000011/1011$

$1\mathrm{.}34$ Because $A-B=A+(-B),$ the subtraction of signed

numbers can be accomplished by adding the

complement. Subtract each of the following pairs of $5-$bit

binary numbers by adding the complement of the

subtrahend to the minuend. Indicate when an overflow

occurs. Assume that negative numbers are represented

in $2\text{'}$s complement.

$($c$)10110-01101,($e$)11100-10101$

$1\mathrm{.}36($a$)A=101010$ and $B=011101$ are $2\text{'}$s complement

numbers. Perform the following operations and indicate

whether overflow occurs.

$($i$)A+B,($ii$)A-B$
