Towards Computer Architecture experts, please help me$,$ try to show all work needed. thank you.

A$)$ Express $-111\mathrm{.}1015$ in IEEE$754$ binary format

please show your work to $8$ bits past the base dot

for the $80$ bit conversions use the same number of bits for $"$ f $"$ as you did for

the $32$ bit conversion

please highlight corresponding bit patterns

state the number of bits for s$,$ e$,$ f for each pattern

a$.32$ bit

b$.80$ bit

B$)64$ bits $($double precision$)$

$-$please show your work to $8$ bits past the base dot
