How good is 17 out of 28?

Answer 1

Putting it into percentage form you will get approximately 61%. To do this you simply divide 17 by 28. So based on percentage I would say that if this were a grade then this is not very good. However if this was say a batting average (in this case the hitter would be hitting .607), then that would be excellent. So to your question of how "good" it is, I'll have to say that it all depends on the circumstances surrounding your data.
