Perform the following conversions using subtraction or division$-$remainder

a$.{170}_{10}$ to base $9$

b$.{4219}_{10}$ to base $5$

Convert the following decimal fractions to binary with a maximum of $6$ places to the

right of the binary point.

a$.84\mathrm{.}605$

b$.2048\mathrm{.}03125$

What decimal value does the $8-$bit binary number $10001100$ have if:

a$.$ It is interpreted as an unsigned number

b$.$ It is on a computer using two's complement representation

Perform the following binary multiplications, assuming unsigned integers $($note: we

didn't talk about multiplication much, but the process is really the same as you would

use for regular base $10$ numbers$).$

a$.{110}_2{10}_2$

b$.10\mathrm{.}012100000\mathrm{.}12$
