Is there any countable noun which is a synonym of 'rating'?

What noun can be used to describe how many times something has been rated?

For voting, you can say "one vote" or "two votes".

For liking (Facebook), you can say "one like" or "two likes".

For rating, I don't think someone would say "one rate" or "two rates".

What's the right word in this case?

Solution 1:

If you are referring to the number of times it has been rated, the countable noun would be ratings.

This post has received 5 positive ratings and 2 negative ratings.

Solution 2:

One would usually say:

A rating of two, a rating of one

E.g.

"The washing machine had a rating of five stars."
