Math conversion question 10 stars to 5 stars

Ok so I'm adding a star rating to my movies in iTunes using IMDB. IMDB uses a 10 star rating and iTunes uses a 5 star rating system. I need the mathematical formula to convert what n/10 stars would be in n/5. For example, a movie is rated 7.3 in IMDB and I want add the rating in iTunes, which allows 5 star max… is the formula 7.3 / 10 * 5 ?

Thanks!

(S/10)*5 would equal S/2 so just divide IMDB by 2.

Bog has done this on several questions and has been reported.

Wozzoa. :)

Let x = the amount of stars you would give on IMDB
Let y = the amount of stars you would give on iTunes

y= x/2

Oh...puh-leeeze...not you again!
