30/48 = 62.5%
The fraction 30/48 represents 62.5%, a little more than three-fifths of a whole. You might see a value like this when 30 out of 48 students turn in an assignment, 30 of 48 seats are filled, or 30 of 48 items in a shipment pass inspection.
To picture it quickly, imagine a bar divided into eight equal sections, with five sections shaded. That gives a useful estimate because 62.5% is five-eighths, so it is noticeably above half but well below three-quarters.
A common mistake is to think 30/48 is close to 50% just because 30 is near half of 48. In fact, half of 48 is 24, so having 30 parts means the amount is considerably more than half.
