27/40 = 67.5%
A value like 67.5% could describe how much of a phone battery remains or how many questions someone got right on a quiz. The fraction 27/40 is a little more than two-thirds.
To picture it quickly, imagine 40 equal squares with 27 shaded. That’s close to shading about 7 out of every 10 squares, but just a little less.
A common point of confusion is treating 67.5% as the same as 67.5 out of 100 whole items. It means 67.5 out of every 100 parts, so the actual number of items depends on the total.
