The fraction 20/38 is equal to 52.63% when converted to a percentage. This means that if you had 38 items and took 20 of them, you'd have about 52.63% of the total. It's a bit more than half, but not quite as much as 55% or three-fifths.
In everyday life, you might see this percentage in various situations. For example, if a weather forecast says there's a 52.63% chance of rain, it means it's slightly more likely to rain than not. Or if a sports team wins 20 out of 38 games in a season, their winning percentage would be 52.63%.
