$9$s$/10$s Complement, Binary Multiplication and Division

$1.$ Convert the following decimal numbers to the $9$s complement:

a$.89$

b$.658203$

c$.824321$

d$.$ Perform subtraction using $9$s complement on $26-18$

$2.$ Convert the following decimal numbers to the $10$s complement:

a$.65$

b$.327$

c$.7643$

d$.$ Perform subtraction using $10$s complement on $432-567$

$3.$ Perform the following multiplications. Assume that all values are unsigned

numbers. $($No problem with unsigned $($always positive$)$ numbers, just use the same

standard techniques as in base $10.)$

a$.1010*0110$

b$.1101*1110$

c$.110101*1001$

d$.1100101\backslash$times $111101$
