When I saw a problem on the site, it had a 2.6 rating. Since I really liked the problem, I voted 5 for it, and saw that the rating went from 2.6 to 2.75.

1) How many people voted for it before I did?

2)What would the rating of this problem be if two more people voted 5 for this problem?

15 people before you.

the average would go up to 3.

Since 5 is the lowest common multiple to turn 0.6 into a whole number(which the rating system is based on). I trial-and error-ed multiples of 5 until I found one where an additional 1 sample of 5 rating would add 0.15
