246/300 = 82%
A fraction like 246/300 can describe a survey where 246 out of 300 people choose the same answer. It could also represent an attendance rate, a test score, or the percentage of products that pass a quality check: 82%.
To picture 82% quickly, imagine a group of 100 items with about 82 shaded and 18 unshaded. It is a little more than four-fifths, so you can estimate it as close to 80% while remembering that it is slightly higher.
A common mistake is thinking 246/300 is only about 50% because 246 is not close to 300 at first glance. The important comparison is how much of the whole 300 the 246 represents, not whether the numerator and denominator look similar.
