The fraction 23/30 is equal to 76.67% when converted to a percentage. This means that if you had a pie cut into 30 slices and took 23 of them, you'd have about three-quarters of the whole pie. It's a pretty big chunk, more than half but not quite all of it.
In everyday life, you might see this percentage used in various situations. For example, if 23 out of 30 students passed a test, the teacher could say that 76.67% of the class succeeded. Or if you're looking at weather forecasts, a 76.67% chance of rain would mean it's pretty likely to rain, but not a sure thing. It's a useful way to express parts of a whole in terms that are easy for most people to understand quickly.
