17/20 = 85%
A value like 17/20, or 85%, might show up as a score on a 20-question quiz or as the share of customers who liked a product. It tells you that most of the group met the goal, though a few did not.
To picture it quickly, imagine 20 equal squares with 17 shaded in. It’s a little less than nine-tenths, so you can estimate it as close to 90%.
One common mix-up is treating 85% as 85 items, no matter how large the group is. The percentage stays the same, but the actual number depends on how many items there are altogether.
