$[10$ marks$]$ For this question you will be working with binary and decimal numbers.

You should consider the numbers as mathematical values, l$.$e$.$ there is no limit to the number of digits in the calculations or the solutions.

Show your work for the calculations. You may directly convert to and from positive decimal integer values and bit sequences. For example, you may go directly from $15$ to to $11112$ without showing any additional steps.

For questions that require calculations involving binary numbers, all work should be shown in terms of binary numbers. The work of your solutions may not convert the values to decimal numbers. You may do those conversions yourself to check your answers.

All of your answers must be precise numbers. This means in the case of fractional values, you should show the fraction or its equivalent using a radix point.

Note that you can represent integers and rational numbers exactly in any base. Justas the decimal number system has rational numbers that are represented with a repeating pattern after the decimal point, e$.$g$.\frac{1}{3}=0\mathrm{.}3$ some rational numbers in binary will have repeating patterns after the radix point. To be clear $\frac{1}{3}l=0\mathrm{.}3.$

$($a$)$ Convert $10110011110122^4$ to decimal.

$($b$)$ Convert $50\mathrm{.}601562510$ to binary. Your answer should be shown as a binary number with a radix point

$($c$)$ Convert $2122510$ to binary. Your answer should be shown as a binary number with a radix point.

$($d$)$ Calculate the sum of these binary numbers$91\mathrm{.}01001122^{-4}+1\mathrm{.}101101122^{-6}$ Your final answer must be shown using normalized representation.

$($e$)$ Calculate the product of these binary numberss $(1\mathrm{.}1011122^8)*(1\mathrm{.}10122^{-5}).$ Your final answer must be shown using normallzed representation.
