Random math questionss?

Hey guys. So, If I have a number that is a percentage (1-100) and I also have a range, for example, 0-15, how can I convert the percentage into the range? For example, 0 percent would be 0 and 100 percent would be 15. Don't really know how to explain this, but .. how would i do it?

 

ALSO, If I have a number between -1 and 1, how can I convert that to a percentage? -1 being 0 percent 1 being 100 percent.

For the first, you multiply the number by 0.15

 

For the second, you add 1 and then multiply by 50.

Thanks. I ended up getting the first but the second.. yeah. thanks.

(15 / 100) * percentage = value out of 15

e.g. 45% = (15 / 100) * 45 = 6.75

 

value out of 15 / (15 / 100) = percentage

e.g. 6.75 = 6.75/(15/100) = 45%

I dont think that the second version is correct

 

take 6.75...

6.75 + 1 = 7.75 * 50 = 387.5

Number between -1 and 1.

6.75 is not a number between -1 and 1.

Number between -1 and 1.

6.75 is not a number between -1 and 1.

Or right, thought you meant converting back the other way.

My bad.
