Full of Titanium go-fast bits!
Mind block or something, help me out here.
range one = 0 to 65,536
range two = -150 to +150
value in range one (35325) = what value in range two?
Steps needed to work this out? they told me I needed pay attention in maths if I wanted to work in computers... I didn't believe them :S

That question doesn't make any sense.

I have a value in one range, i need it converted to its equivalent in the other range..

First range would make more sense if it was 0 to 65535 (FFFF hex), ie, 65536 distinct values. I'd assume that that's just an error in the form of the question.
Assuming you have no other information than that brain-dead question form, presumably written by someone who was too stupid to get a real job and has therefore ended up teaching, I'd expect that you're supposed to be using an unsigned 16-bit number to represent a range of -150 to 150 decimal.
Which means that you divide 301 decimal (the number of values in your represented range) by 65536 decimal (the number of values in your 16-bit integer) and then multiply the result by 35325 and add the result to your minimum value.
In other words, 12.24.
But, really, I wouldn't have a clue what I'm on about here. Pay no attention to anything I write.
(Edited 302 to 301. See, I told you I had no clue. And edited the result to be added to -150, etc. This whole thread is stupid.)

12.
35325 is 53.9%of the way up the range.
12 is 53.9% of the way through the second range.
I hope
Edit: I rounded to two decimal places, so JR above may be more accurate...

I'd be inclined to keep some more precision in the answer. If the question's assuming that 16 bits are being used to represent the range, one can safely assume that one might as well use the precision available.
For extra points, if I were the lecturer, I'd expect my students to point out how many significant decimal digits 16 binary digits worth of precision over that range gives.
But lecturers are, on the whole, lazy and stupid.

fuckin grumpy leave me alone
forget that, just write an essay on what you did in the weekend
it will be more intersting, and you might get sum marks for trying

Perhaps I should clarify - I'm not a student, this is not an assignment or anything.. I'm just writing some software for a little home project that I've built.
yes I believe the answer to be 11.707 (mV if your interested), I think slowfox is the winner.. Percentages.. why does the human brain often block out the simplest answer?

yeah, pretty much Dan , could not get my head round pyroformic, endothermic, exothermic reaction, Hydraulics and measuration ,chemistry ,physics, , mecahics and all that shit.
have to say that all that shit we were taught 20+ years ago , never used it once operationally...

When I ran it to full decimal places (as far as the calc would allow), I got 11.705017089...

The question is still retarded. You better make sure you capture any assumptions you make in answering the question. Like are these integer ranges or real? And what is the relationship between the ranges? Is it linear, logarithmic or something else? There are many ways that values in one range could be mapped to values in the other? It'd be inefficient but you could even do it randomly with a lookup table.
Who's asking the question?
Edit: Oh I see now. Back in my box
