Convert the following decimal number $(2941\mathrm{.}48){?}_{10}$ into hexadecimal.

Add the two binary numbers by showing clearly the carry bits and results:

$1100111+1110101=?$

$1101000-110111=?$ Show the borrow bits.

Multiply $11011$ x $1111=?$ Show the partial sums and final answer.

Divide $10100010$ by $111$

now your work.
