WRITING FRACTIONS WITH A DENOMINATOR OF 2 IN DECIMAL FORM

On the next web exercise (finding the average of two signed numbers),
you will need to report your answers in decimal form.
All your answers will be fractions with a denominator of [beautiful math coming... please be patient] $\,2\,$,
and you should be able to convert them to a decimal without having to pull out your calculator!

To convert (say) [beautiful math coming... please be patient] $\,\displaystyle\frac{15}{2}\,$ to decimal form, go through this thought process:

How many times does [beautiful math coming... please be patient] $\,2\,$ go into [beautiful math coming... please be patient] $\,15\,$?
Answer:   It goes in [beautiful math coming... please be patient] $\,7\,$ times, with [beautiful math coming... please be patient] $\,1\,$ left over.
The answer is [beautiful math coming... please be patient] $\,7.5\,$.

Here are the details: [beautiful math coming... please be patient] $$\frac{15}2 \ =\ \frac{14+1}2 \ =\ \frac{14}2 + \frac12 \ =\ 7 + \frac 12 \ =\ 7 + 0.5 \ =\ 7.5$$

To convert a negative fraction (say, [beautiful math coming... please be patient] $\,\displaystyle-\frac{19}{2}$) to decimal form, go through this thought process:

Firstly, the answer will be negative.
How many times does [beautiful math coming... please be patient] $\,2\,$ go into [beautiful math coming... please be patient] $\,19\,$?
Answer:   It goes in $\,9\,$ times, with $\,1\,$ left over.
The answer is [beautiful math coming... please be patient] $\,-9.5\,$.

Of course, if [beautiful math coming... please be patient] $\,2\,$ goes in evenly, then you don't need a decimal at all to report your answer.
For example, [beautiful math coming... please be patient] $\,-\frac{16}2 = -8\,$.
