The fraction 17/30 is equal to 56.67% when converted to a percentage. This means that if you had a pie cut into 30 slices and took 17 of them, you'd have about 57% of the whole pie. It's a bit more than half, but not quite two-thirds.
In everyday life, you might see this percentage used in various situations. For example, if 17 out of 30 students in a class passed a test, the teacher could say that 56.67% of the class succeeded. Or if a weather forecast predicts a 56.67% chance of rain, you'd know there's a slightly better than even chance it might rain that day.
